Description

吹吸装置及装配吹吸装置的方法Blowing device and method of assembling the same 技术领域Technical field
本发明涉及一种兼具吹功能和吸功能的吹吸装置。本发明还涉及一种装配吹吸装置的方法。The present invention relates to a suction and suction device having both a blowing function and a suction function. The invention also relates to a method of assembling a blowing device.
背景技术Background technique
吹吸装置是一种常见的电动户外清洁工具，主要用于树叶等垃圾的清理和收集。吹吸装置通常具有吹模式和吸模式，在吹模式下，吹吸装置向外吹出风，可以将地面上散落的树叶集中。而在吸模式下，吹吸装置产生吸力，配合收集装置可以将树叶吸至收集装置里，从而避免手动清扫，达到节省人力和时间的目的。收集装置可以是体现便携性的随身携带的垃圾袋，也可以是体型较大的一次性可存储较多树叶的垃圾桶。因此，用户可根据实际工作情况，自由地选择吹吸装置处于吸模式还是吹模式。这样优势之处在于：用户仅需要一台吹吸装置，即可完成树叶的集中及收集处理，不需要其他额外的工具。The suction device is a common electric outdoor cleaning tool, mainly used for cleaning and collecting garbage such as leaves. The suction device usually has a blowing mode and a suction mode. In the blowing mode, the blowing device blows out the wind outward, and the leaves scattered on the ground can be concentrated. In the suction mode, the suction device generates suction, and the collecting device can suck the leaves into the collecting device, thereby avoiding manual cleaning and saving manpower and time. The collecting device may be a carry-on garbage bag that is portable, or a large-sized one-time garbage bin that can store more leaves. Therefore, the user can freely select whether the suction device is in the suction mode or the blowing mode according to the actual working conditions. This has the advantage that the user only needs a single suction device to complete the concentration and collection of the leaves without the need for additional tools.
而传统的仅能进行吹风功能的吹风装置，由于不具备吸风模式，用户在利用吹风把树叶集中后，仍然需要借助其他工具把集中的树叶收集入收集装置。此处的其他工具例如吸尘器、手动工具等。因此完成工作需要用到的工具较多，操作比较繁琐。这是吹吸装置相较于传统的吹风装置有利的地方。In the conventional air blowing device which can only perform the air blowing function, since the suction mode is not provided, the user still needs to collect the concentrated leaves into the collecting device by using other tools after concentrating the leaves by the air blowing. Other tools here such as vacuum cleaners, hand tools, and the like. Therefore, more tools are needed to complete the work, and the operation is cumbersome. This is where the suction device is advantageous over conventional blowers.
但是吹吸装置也有不利的缺点。吹吸装置由于实现吹和吸两种不同的功能，需要兼顾两者的特点，同时还要尽可能提升吹风及吸风的性能表现，无法直接沿用吹风机的结构。另外吹吸装置需要在吹和吸两种模式之间频繁切换，因此模式切换的过程必须尽可能的简化，利于用户的使用，提升用户体验。However, the suction device also has disadvantages. Since the blowing device realizes two different functions of blowing and sucking, it is necessary to take into consideration the characteristics of both, and at the same time, to improve the performance of the blowing and suction as much as possible, and the structure of the hair dryer cannot be directly used. In addition, the blowing device needs to frequently switch between the blowing mode and the suction mode, so the process of mode switching must be simplified as much as possible, which is beneficial to the user's use and enhances the user experience.
如美国专利US4870714公开了一种吹吸装置，其具备了吹功能和吸功能。在执行吹风功能的时候，吹风管连接在风扇的径向位置，而当执行吸风功能的时候，吸风管连接在风扇的轴向位置。如此设计有以下几个缺点：1.首先吹风管和吸风管不是同一根管子，因此用户需要配备吹风管和吸风管两根管子才能进行实现吹吸功能，如果丢失管子会造成无法执行某项功能的后果，而且两根管子也必然会占用更大的储存空间和成本。2.在进行吹吸转换的时候，必须先拆下安装的吹风管/吸风管，然后装上吹风管/吹风管。也就是说，在吹吸模式转换的时候需要更换风管，这给用户操作带来了极大不便。3.吹风管和吸风管需要安装在吹吸装置上不同的位置，由此造成整体结构的复杂。因此吹吸装置 的结构必须得到优化，以使结构更紧凑，用户操作更方便，整个吹吸装置更小巧，满足用户的需求。A blow suction device having a blowing function and a suction function is disclosed, for example, in U.S. Patent No. 4,707,714. When the blowing function is performed, the blowing pipe is connected to the radial position of the fan, and when the suction function is performed, the suction pipe is connected to the axial position of the fan. The design has the following disadvantages: 1. First, the blowing pipe and the suction pipe are not the same pipe, so the user needs to have two pipes of the blowing pipe and the suction pipe to realize the blowing function, and if the pipe is lost, the pipe cannot be used. The consequences of performing a certain function, and the two tubes will inevitably take up more storage space and cost. 2. When performing the suction and suction conversion, the installed blow pipe/suction pipe must be removed first, and then the blow pipe/dry pipe must be installed. That is to say, the air duct needs to be replaced when the blow mode is switched, which brings great inconvenience to the user operation. 3. The blowing tube and the suction tube need to be installed at different positions on the suction device, thereby causing the complexity of the overall structure. Therefore, the suction device The structure must be optimized to make the structure more compact, user-friendly, and the entire suction device is smaller enough to meet the needs of the user.

具体实施方式detailed description
下面结合附图对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings, in which the advantages and features of the invention can be more readily understood by those skilled in the art.
图1所示是本发明一实施例的吹吸装置1的整体示意图。吹吸装置1是一种常见的花园工具，用于执行清洁工作。吹吸装置1可以利用吹风功能将散落 的树叶集中起来，也可以利用吸风功能把树叶吸入指定的垃圾收集装置，从而达到清洁的目的。因此吹吸装置1至少具有两种工作模式。当吹吸装置1处于第一工作模式时，吹吸装置1执行吹风功能，而当吹吸装置1处于第二工作模式时，吹吸装置1执行吸风功能。因此第一工作模式也可以称之为吹模式，第二工作模式也可以称之为吸模式。吹吸装置1可根据用户的实际需求，可选择地在吹模式或者吸模式下工作。吹吸装置1整体沿图1中箭头A所示的方向延伸，定义该方向为纵向。吹吸装置1主要包括主体10以及可连接主体10的风管2。主体10包括外壳14，外壳14大致沿纵向延伸。外壳14用于包覆在外部，起到保护作用。在不同的实施例中，外壳14可以是一体构造形成的壳体，也可以是多个半壳体构成的整体，半壳与半壳之间通过螺丝等固定元件固定连接。外壳14可以包括一层或者内外多层形式的壳体组，也可以包括多个保护各自元件的壳体。风管2可连接主体10。风管2内部中空，用于提供空气流通，使空气从风管2吹向外界或者从外界吸入。在本实施例中，风管2可拆卸地连接主体10。当平时不需要使用吹吸装置1时，可以把风管2与主体10拆卸下并分离开，能够减少吹吸装置1整体的长度尺寸。当需要使用吹吸装置1时，可以把风管2与主体10连接，从而执行相应的吹风功能或吸风功能。由图1可见，风管2位于主体10的纵向前端。Fig. 1 is a schematic overall view of a suction device 1 according to an embodiment of the present invention. The suction device 1 is a common garden tool for performing cleaning work. The suction device 1 can be scattered by using the blowing function The leaves are concentrated, and the leaves can also be sucked into the designated garbage collection device by means of suction to achieve the purpose of cleaning. Therefore, the suction device 1 has at least two modes of operation. When the suction device 1 is in the first operational mode, the suction device 1 performs a blowing function, and when the suction device 1 is in the second operational mode, the suction device 1 performs a suction function. Therefore, the first working mode can also be called a blowing mode, and the second working mode can also be called a suction mode. The suction device 1 can be selectively operated in a blow mode or a suction mode according to the actual needs of the user. The suction device 1 as a whole extends in the direction indicated by the arrow A in Fig. 1, and the direction is defined as the longitudinal direction. The suction device 1 mainly includes a main body 10 and a duct 2 to which the main body 10 can be connected. The body 10 includes a housing 14 that extends generally longitudinally. The outer casing 14 is used to cover the outside for protection. In different embodiments, the outer casing 14 may be a housing formed by an integral structure, or may be a whole of a plurality of half-shells, and the half-shell and the half-shell are fixedly connected by a fixing component such as a screw. The outer casing 14 may comprise a single or a plurality of inner and outer layers of the housing set, and may also include a plurality of housings that protect the respective components. The duct 2 can be connected to the main body 10. The air duct 2 is hollow inside to provide air circulation, and the air is blown from the air duct 2 to the outside or inhaled from the outside. In the present embodiment, the duct 2 is detachably coupled to the main body 10. When it is not necessary to use the suction device 1, the air duct 2 and the main body 10 can be detached and separated, and the overall length of the air suction device 1 can be reduced. When it is desired to use the air suction device 1, the air duct 2 can be connected to the main body 10 to perform a corresponding air blowing function or suction function. As can be seen from Figure 1, the duct 2 is located at the longitudinal front end of the body 10.
吹吸装置1包括气流产生装置。如图2所示，气流产生装置收容于外壳14内，并可操作地产生气流。气流产生装置产生的气流能够沿一定的方向移动。在本优选的实施例中，气流产生装置可控制地产生沿不同方向移动的气流。例如，该气流产生装置可产生沿一向纵向前端方向移动的气流，也可以产生沿与向纵向前端方向相反的纵向后端方向移动的气流。气流移动的不同方向之间可以呈180度的夹角。在其他实施例中，气流移动的不同方向之间也可以呈其他角度，例如60、90、120、150度等。如图2所示，常见的气流产生装置包括了可旋转的风扇3以及用于驱动风扇3旋转的马达4。马达4用于提供旋转动力。按动力来源划分，马达4可以是气动马达，也可以是电力驱动的电动马达，也可以是以汽油为燃料的汽油马达。电动马达包括了常见的碳刷马达或者是无刷马达。在本实施例中，马达4具有定子40以及可相对定子40转动的转子49。定子40被支撑结构46固定支撑。支撑结构46包括了沿纵向分开设置的前支架 461和后支架462。前支架461和后支架462各自支撑起定子40。前支架461和后支架462之间还通过螺栓463固定连接。转子49包括沿轴线41延伸的马达轴42。在本实施例中，轴线41沿纵向延伸。转子49带动马达轴42围绕轴线41做旋转运动。马达轴42连接风扇3，从而带动风扇3相应的转动。当然，风扇3与马达轴42之间也可以设置齿轮等传动机构。可选择地围绕轴线41沿顺时针方向旋转，也可以沿逆时针方向旋转，如图2中的双箭头B所示。当然在其他实施例中，马达4也可以只沿一个方向旋转。在其他的实施例中，气流产生装置不限于包含风扇3和马达4，例如采用磁力等新动力技术进行驱动，进而产生气流的方式。The suction device 1 includes an air flow generating device. As shown in Figure 2, the airflow generating device is housed within the outer casing 14 and is operable to generate an air flow. The airflow generated by the airflow generating device can move in a certain direction. In the preferred embodiment, the airflow generating means controllably produces airflow that moves in different directions. For example, the airflow generating means may generate an air flow moving in the direction of the longitudinal longitudinal end, or may generate an air flow moving in a direction opposite to the longitudinal rear end opposite to the longitudinal front end. The different directions of airflow movement can be at an angle of 180 degrees. In other embodiments, different directions of airflow movement may also be at other angles, such as 60, 90, 120, 150 degrees, and the like. As shown in FIG. 2, a common airflow generating device includes a rotatable fan 3 and a motor 4 for driving the rotation of the fan 3. The motor 4 is used to provide rotational power. Divided by power source, the motor 4 can be a pneumatic motor, an electric motor driven by electric power, or a gasoline motor fueled by gasoline. Electric motors include common carbon brush motors or brushless motors. In the present embodiment, the motor 4 has a stator 40 and a rotor 49 rotatable relative to the stator 40. The stator 40 is fixedly supported by the support structure 46. The support structure 46 includes front brackets that are spaced apart in the longitudinal direction 461 and rear bracket 462. The front bracket 461 and the rear bracket 462 each support the stator 40. The front bracket 461 and the rear bracket 462 are also fixedly connected by bolts 463. The rotor 49 includes a motor shaft 42 that extends along an axis 41. In the present embodiment, the axis 41 extends in the longitudinal direction. The rotor 49 drives the motor shaft 42 to make a rotational motion about the axis 41. The motor shaft 42 is connected to the fan 3 to drive the corresponding rotation of the fan 3. Of course, a transmission mechanism such as a gear may be disposed between the fan 3 and the motor shaft 42. Optionally, it can be rotated clockwise about axis 41 or counterclockwise, as indicated by double arrow B in FIG. Of course, in other embodiments, the motor 4 can also be rotated in only one direction. In other embodiments, the airflow generating device is not limited to the manner in which the fan 3 and the motor 4 are included, for example, driven by a new power technology such as a magnetic force to generate an airflow.
风扇3可被旋转地驱动从而产生气流。在本实施例中，风扇3连接马达轴42，从而受马达轴42的驱动相应旋转。风扇3和马达4在主体10内大致纵向前后分布。风扇3更靠近纵向前端。马达4更靠近纵向后端。风扇3至少包括轴流风扇。轴流风扇能够围绕风扇轴线39旋转，并产生平行于风扇轴线39延伸方向流动的气流。在其他实施例中，风扇3可以由多级的轴流风扇组合而成，也可以仅有一级的轴流风扇构成。另外，风扇3也可以有其他类型的风扇多级组合，但是其中至少有一级是轴流风扇。在其他的实施例中，风扇3也可以是由混流风扇形成。因为混流风扇也能产生沿风扇轴线39延伸方向移动的气流。在本实施例中，如图3所示，风扇3由一级的轴流风扇构成。风扇3包括轮毂31和若干个设置在轮毂31上的叶片32。轮毂31上设有连接孔33与马达轴42配接。连接孔33优选的具有扁方形状，正好与马达轴42上的扁方结构配合，从而使风扇3与马达轴42构成无相对旋转。值得注意的是，连接孔33是具有一定的纵向厚度的通孔，马达轴42沿纵向***部分的连接孔33中，而不是全部连接孔33都被马达轴42***。这样设计的目的是连接孔33需要与其他元件配接。而在其他实施例中，连接孔33和马达轴42上也可以设置相应的花键结构，从而实现风扇3与马达4无相对转动的连接。叶片32沿轮毂31的径向延伸。叶片32的一端连接在轮毂31的周向表面34，该端为连接端35，与该连接端35相对的另一端为自由端36。叶片32可以与轮毂31一体成型，也可以与轮毂31固定连接。位于连接端35和自由端36之间的侧边呈弯曲设置使得整个叶片32大致卷曲状态。叶片32沿连接端35与自由端36的连线方向(也就是风 扇3的径向)螺旋设置，使得叶片32整体呈类似螺旋阶梯结构，因此该连接端35和自由端36并非位于同一平面。叶片32沿风扇3的周向均匀的分布。在优选的实施例中，叶片32的数量为12个，当然也可以是9、10、11、13、14等。该若干个叶片32的螺旋方向均保持一致。叶片32随轮毂31一同旋转。在本实施例中，轴流风扇的风扇轴线39是与马达轴42的轴线41重合。当然在其他实施例中，轴流风扇的风扇轴线39与马达轴42的轴线41是不重合设置的。在本实施例中，轴流风扇旋转形成的平面与轴线41基本垂直。空气从风扇3的一侧穿过该平面，并移动至风扇3的另一侧。定义风扇3的起始一侧为上游区域，而另一侧为下游区域。在本实施例中，上游区域和下游区域沿纵向前后分布。空气从上游区域穿过风扇3并移动至下游区域，所以风扇3位于空气流通经过的路径中。在本实例中，由于马达4与风扇3纵向排列，因此马达4同样位于空气流通经过的路径中。另外值得注意的是，风扇3可选择地沿不同方向的第一方向和第二方向转动。从而使风扇3旋转产生不同方向移动的气流。特别强调的是，气流的不同移动方向是指相对风扇3而言。具体地，是指在第一工作模式下气流通过风扇3旋转形成的平面时的方向与第二工作模式下气流通过风扇3旋转形成的平面的是方向是不相同的。在本实施例中，风扇3可控制地围绕风扇轴线39沿顺时针或者逆时针方向转动，如图2中的双箭头B所示。这是基于风扇3始终围绕同一风扇轴线旋转的前提下进行的。而在另外的实施例中，风扇3也可以围绕不同的风扇轴线进行旋转。例如，在某一时间段内，风扇3围绕第一风扇轴线旋转，因此风扇3向第一方向旋转；而当在另一时间段内，风扇3又围绕第二风扇轴线旋转，第一风扇轴线与第二风扇轴线可以平行设置或者呈一定夹角设置。这里的夹角可以是90度或者锐角或者其他角度。另外，在本实施例中，控制风扇3转动方向的是马达4，马达4能够使风扇3产生向某一方向移动的气流，也能够使风扇3产生向另外一方向移动的气流。在本实施例中，由于马达4动力连接风扇3，因此控制马达4的旋转方向即可以控制风扇3的转动方向。控制马达4正向旋转即能使风扇3沿第一方向转动，而控制马达4反向旋转即能使风扇3沿第二方向转动。在本实施例中，风扇3的第一方向为顺时针方向，风扇3的第二方向为逆时针方向。换句话说，第一方向与第二方向正好相反。在另外的实施例中，马达4与风扇3之间还可以设 有换向离合器。通过改变换向离合器的离合位置或/与状态，带动风扇3向不同方向旋转。而无论风扇3向哪个方向旋转，马达4可以仅单向地转动以传递动力。The fan 3 can be rotationally driven to generate an air flow. In the present embodiment, the fan 3 is coupled to the motor shaft 42 so as to be correspondingly rotated by the drive of the motor shaft 42. The fan 3 and the motor 4 are distributed longitudinally forward and backward in the main body 10. The fan 3 is closer to the longitudinal front end. The motor 4 is closer to the longitudinal rear end. The fan 3 includes at least an axial fan. The axial fan is rotatable about the fan axis 39 and produces an air flow that flows parallel to the direction in which the fan axis 39 extends. In other embodiments, the fan 3 may be composed of a multi-stage axial fan or a single-stage axial fan. In addition, the fan 3 can also have other types of fan multi-stage combinations, but at least one of them is an axial fan. In other embodiments, the fan 3 may also be formed by a mixed flow fan. Because the mixed flow fan can also generate airflow that moves in the direction in which the fan axis 39 extends. In the present embodiment, as shown in Fig. 3, the fan 3 is constituted by a primary axial fan. The fan 3 includes a hub 31 and a plurality of blades 32 disposed on the hub 31. The hub 31 is provided with a connecting hole 33 that is coupled to the motor shaft 42. The connecting hole 33 preferably has a flat shape which fits exactly with the flat structure on the motor shaft 42, so that the fan 3 and the motor shaft 42 are formed without relative rotation. It is to be noted that the connecting hole 33 is a through hole having a certain longitudinal thickness, and the motor shaft 42 is inserted into the connecting hole 33 of the longitudinal direction portion, and not all of the connecting holes 33 are inserted by the motor shaft 42. The purpose of this design is that the connection holes 33 need to be mated with other components. In other embodiments, the corresponding spline structure may also be provided on the connecting hole 33 and the motor shaft 42, so that the fan 3 and the motor 4 are connected without relative rotation. The vanes 32 extend in the radial direction of the hub 31. One end of the vane 32 is coupled to a circumferential surface 34 of the hub 31, the end being a connecting end 35, and the other end opposite the connecting end 35 being a free end 36. The vane 32 may be integrally formed with the hub 31 or may be fixedly coupled to the hub 31. The side edges between the connecting end 35 and the free end 36 are curved so that the entire blade 32 is substantially curled. The blade 32 is along the line connecting the connecting end 35 and the free end 36 (that is, the wind The radial direction of the fan 3 is helically arranged such that the blade 32 as a whole has a spiral-like stair structure, so that the connecting end 35 and the free end 36 are not in the same plane. The blades 32 are evenly distributed along the circumferential direction of the fan 3. In a preferred embodiment, the number of blades 32 is twelve, although it may be 9, 10, 11, 13, 14, or the like. The spiral directions of the plurality of vanes 32 are all consistent. The blades 32 rotate with the hub 31. In the present embodiment, the fan axis 39 of the axial fan coincides with the axis 41 of the motor shaft 42. Of course, in other embodiments, the fan axis 39 of the axial fan is not coincident with the axis 41 of the motor shaft 42. In the present embodiment, the plane formed by the rotation of the axial fan is substantially perpendicular to the axis 41. Air passes through the plane from one side of the fan 3 and moves to the other side of the fan 3. It is defined that the starting side of the fan 3 is the upstream area and the other side is the downstream area. In the present embodiment, the upstream region and the downstream region are distributed back and forth in the longitudinal direction. Air passes from the upstream region through the fan 3 and moves to the downstream region, so the fan 3 is located in the path through which the air circulates. In the present example, since the motor 4 and the fan 3 are longitudinally arranged, the motor 4 is also located in the path through which the air circulates. It is also worth noting that the fan 3 is selectively rotatable in a first direction and a second direction in different directions. Thereby the fan 3 is rotated to generate a flow of air moving in different directions. It is particularly emphasized that the different directions of movement of the airflow refer to the fan 3. Specifically, it means that the direction in which the airflow passes through the plane formed by the rotation of the fan 3 in the first operational mode is different from the direction in which the airflow in the second operational mode is formed by the rotation of the fan 3 is different. In the present embodiment, the fan 3 is controllably rotatable about the fan axis 39 in a clockwise or counterclockwise direction, as indicated by the double arrow B in FIG. This is done on the premise that the fan 3 is always rotated about the same fan axis. In still other embodiments, the fan 3 can also be rotated about different fan axes. For example, during a certain period of time, the fan 3 rotates about the first fan axis, so the fan 3 rotates in the first direction; and in another period of time, the fan 3 rotates again around the second fan axis, the first fan axis It may be arranged in parallel with the second fan axis or at a certain angle. The angle here can be 90 degrees or an acute angle or other angle. Further, in the present embodiment, the motor 4 is controlled to control the direction of rotation of the fan 3, and the motor 4 can cause the fan 3 to generate an air flow that moves in a certain direction, and can also cause the fan 3 to generate an air flow that moves in the other direction. In the present embodiment, since the motor 4 is power-connected to the fan 3, the direction of rotation of the motor 4 can be controlled by controlling the direction of rotation of the motor 4. Controlling the forward rotation of the motor 4 enables the fan 3 to rotate in the first direction, and controlling the reverse rotation of the motor 4 enables the fan 3 to rotate in the second direction. In the present embodiment, the first direction of the fan 3 is clockwise, and the second direction of the fan 3 is counterclockwise. In other words, the first direction is exactly the opposite of the second direction. In another embodiment, the motor 4 and the fan 3 may also be provided. There is a reversing clutch. The fan 3 is driven to rotate in different directions by changing the clutch position or/and the state of the reversing clutch. Regardless of which direction the fan 3 rotates, the motor 4 can be rotated only in one direction to transmit power.
如图1和图2所示，主体10还设有用于握持的手柄部9，手柄部9弯曲设置。其两端分别连接于主体10上，从而形成握持空间。在操作吹吸装置1的时候，手柄部9位于吹吸装置1的上方。更具体地，手柄部9位于马达4的上方，如此可以使手柄部9与马达4达到较为理想的重量平衡。优选地，在手柄部9上设有用于控制马达4旋转方向的控制开关91，控制开关91可操作的控制马达4沿顺时针方向旋转或者沿逆时针方向旋转。控制开关91还可以集成其他控制功能，例如调速功能，可以无级或者有级的方式进行调节马达4的转速。调速功能也可以不设置在控制开关91上，而是利用另外的开关进行控制。在优选的实施例中，控制开关91具有至少三个档位，也就是说具有至少三个操作位置。其中，第一操作位置对应于马达4沿顺时针方向旋转的状态或者说对应于风扇3沿第一方向旋转的状态；第二操作位置对应于马达4处于沿逆时针方向旋转的状态或者说对应于风扇3沿第二方向旋转的状态；第三操作位置对应于马达4处于停止工作状态或者说对应于风扇3停止旋转的状态；第三操作位置可以位于第一操作位置与第二操作位置之间，当然也可以位于其他位置。而控制开关91本身并非限制在手柄部9上，也可以位于主体10上的其他位置。在本实施例中，吹吸装置1的手柄末端处还设置有电性接口15，电性接口15固定连接有电源线(图中未示出)。电源线用于配接外部电源提供给吹吸装置1交流动力。此处的外部电源可以是220V的交流电源。在其他实施例中，主体10的电性接口15还可以配接可拆卸的电池包，电池包插接至配接部后提供直流动力给吹吸装置1。电池包是可插拔式或固定式的。并且，电池包的材料优选的是锂电池、镍镉电池等，电池包的电压可以是但不限制于40V、56V。As shown in FIGS. 1 and 2, the main body 10 is further provided with a handle portion 9 for gripping, and the handle portion 9 is curved. The two ends are respectively connected to the main body 10 to form a holding space. When the suction device 1 is operated, the handle portion 9 is located above the suction device 1. More specifically, the handle portion 9 is located above the motor 4, which allows the handle portion 9 and the motor 4 to achieve a desired weight balance. Preferably, the handle portion 9 is provided with a control switch 91 for controlling the direction of rotation of the motor 4, and the control switch 91 is operable to control the motor 4 to rotate in a clockwise direction or in a counterclockwise direction. The control switch 91 can also integrate other control functions, such as a speed control function, to adjust the speed of the motor 4 in a stepless or stepwise manner. The speed control function may not be provided on the control switch 91, but may be controlled by another switch. In a preferred embodiment, the control switch 91 has at least three gear positions, that is to say has at least three operating positions. Wherein, the first operating position corresponds to a state in which the motor 4 rotates in a clockwise direction or a state in which the fan 3 rotates in a first direction; the second operating position corresponds to a state in which the motor 4 is rotated in a counterclockwise direction or corresponds to a state in which the fan 3 is rotated in the second direction; the third operating position corresponds to a state in which the motor 4 is in a stopped state or in a state in which the fan 3 stops rotating; the third operating position may be located in the first operating position and the second operating position Of course, you can also be located elsewhere. The control switch 91 itself is not limited to the handle portion 9, but may be located at other positions on the main body 10. In the present embodiment, the end of the handle of the air suction device 1 is further provided with an electrical interface 15 to which a power cable (not shown) is fixedly connected. The power cord is used to match the external power source to provide AC power to the suction device 1. The external power supply here can be 220V AC power. In other embodiments, the electrical interface 15 of the main body 10 can also be equipped with a detachable battery pack, and the battery pack is inserted into the mating portion to provide DC power to the air suction device 1. The battery pack is pluggable or fixed. Further, the material of the battery pack is preferably a lithium battery, a nickel cadmium battery or the like, and the voltage of the battery pack may be, but not limited to, 40 V, 56 V.
如图2、图4和图5所示，主体10还包括沿纵向排布的接口11和第一开口12。接口11和第一开口12都设置在外壳14上。接口11用于连接风管2，而第一开口12用于与外界连通，气流产生装置产生的气流可以通过该第一开口12从主体10内部向外界移动，或者从外界向主体10内部移动。接口11位于主体10的纵向前端，第一开口12位于主体10的纵向后端。接口11的轮廓与 风管2的轮廓大致相同，用于与风管2连接，从而把风管2与主体10连接起来。接口11附近的主体10上还设有定位结构16。在本实施例中，定位结构16为突出于主体10表面的定位凸块，用于与风管2上的对应卡槽定位配合。As shown in FIGS. 2, 4 and 5, the main body 10 further includes an interface 11 and a first opening 12 which are arranged in the longitudinal direction. Both the interface 11 and the first opening 12 are disposed on the outer casing 14. The interface 11 is for connecting the air duct 2, and the first opening 12 is for communicating with the outside, and the airflow generated by the airflow generating device can be moved from the inside of the main body 10 to the outside through the first opening 12, or from the outside to the inside of the main body 10. The interface 11 is located at a longitudinal front end of the body 10, and the first opening 12 is located at a longitudinal rear end of the body 10. The outline of the interface 11 The duct 2 has substantially the same contour and is used for connection with the duct 2 to connect the duct 2 with the main body 10. A positioning structure 16 is also provided on the body 10 near the interface 11. In this embodiment, the positioning structure 16 is a positioning protrusion protruding from the surface of the main body 10 for positioning and matching with the corresponding card slot on the air duct 2.
风管2用于气流的流通。风管2的一端与接口11相连接，与该端相对的另一端则具有连通外界的管口21。在本实施例中，风管2有且仅有一个。当然，在其他实施例中，风管2也可以由可多段组合形成的一个具有完整吹风或者吸风功能的风管。需要使用风管2的时候，每一段可以连接起来。例如，风管2包括了可拆卸的第一段和第二段，第一段与第二段之间还设有用于固定连接的固定结构。固定结构可以包括设置在第一段上的弹性卡接件，而在第二段的对应位置处则设置配合弹性卡接件的形配件。此处的形配件可以是圆孔，正好可以容纳弹性卡接件***卡接。当然，也可以把弹性卡接件设置在第二段上，而形配件设置在第一段上。要在使用风管2的时候，第一段和第二段可以通过固定结构连接形成完整的风管而进行使用。当不需要使用风管2的时候可以对风管2拆解分成多段储存，从而利于减少占用面积。此外，也可以在风管2上额外加装起辅助功能的附件，例如在风管2的管口21处安装可改变管口21形状的附件，比如使风管截面积变宽的附件。又例如在风管2的管口21处安装改变风管出风方向的附件，使管口21的朝向产生一定程度的改变，从而使其可以对更宽的方向进行吹风，从而提高工作效率。在本实施例中，该风管为笔直延伸的直管，其端部并没有管径变化的部分。当然也可以在风管的端部或者风管整体设置管径变化的部分，便于调节出风速度。例如可以在风管2上设置半径渐变的锥形结构。在优选的实施例中，如图23和图24所示，风管2整体是锥形管。风管2的一端具有较大的截面积，而另一端具有相对较小的截面积。又例如可以在风管2设置弯折部，使风管2的延伸方向在该弯折部发生转折。在优选地实施例中，弯折部靠近风管2的管口21设置。另外为了减少握持的压力，在风管2的弯折部附近设置支撑在地面的滚轮。如此在执行吹吸功能的时候，风管2的重量被滚轮支撑有效分流。出于安规的要求，风管2的长度范围在500毫米至800毫米之间，优选地在550毫米左右。而风管2的截面积范围在5000平方毫米至15000平方毫米之间，优选地在8000平方毫米左右。如图4和图5所示，风管2的一端具有连接主体10的连接口25，另一端设置有连通外界的 管口21。在图1的实施例中，风管2连接主体10的连接口25具有较小的截面积，优选地其直径为100毫米，而风管2的管口21具有较大的截面积，优选地其直径为110毫米。因此连接口25的截面积小于管口21的截面积。当风管2连接到主体10后，风管2的管口21和第一开口12同样在垂直于风扇轴线39的平面上的投影至少部分重合。管口21形成的截面大致与水平线成一定夹角。当位于吹吸装置1的纵向后端的手柄部9被用户握持风管2后，由于用户的手自然垂放的位置并非贴近地面，而是距离地面约有几十公分到1米左右。而位于吹吸装置1的纵向前端的风管2的管口21由于有与水平线一定夹角的存在，可以使管口21比较贴近地面。风管2可以与接口11可拆卸的连接，也可以始终固定连接。在本实施例中，无论是吹模式还是吸模式，风管2均与主体10之间通过接口11连接，不需要在不同模式下进行切换，因此风管2可以与主体10固定连接。在运输或者储藏的时候把风管2和主体10分开，以减少占用体积。风管2的管口21也指第二开口，第二开口是相对外壳14的第一开口12而言。因此在本实施例中，主体10仅有一个与风管2连接的接口11。The duct 2 is used for the circulation of airflow. One end of the air duct 2 is connected to the interface 11, and the other end opposite to the end has a nozzle 21 that communicates with the outside. In the present embodiment, there are one and only one duct. Of course, in other embodiments, the duct 2 may also be formed by a multi-stage combination of a duct having a complete blowing or suction function. When the duct 2 is needed, each section can be connected. For example, the duct 2 includes a detachable first section and a second section, and a fixed structure for a fixed connection is also provided between the first section and the second section. The fixing structure may include an elastic clip disposed on the first segment, and a fitting fitting the elastic clip at a corresponding position of the second segment. The shaped fitting here can be a circular hole that can accommodate the insertion of the elastic snap-in piece. Of course, it is also possible to arrange the elastic clip on the second section and the profile on the first section. When the duct 2 is to be used, the first section and the second section can be connected by a fixed structure to form a complete duct. When the duct 2 is not needed, the duct 2 can be disassembled and divided into a plurality of sections, thereby facilitating the reduction of the occupied area. In addition, it is also possible to additionally add an auxiliary function attachment to the duct 2, for example, an attachment that changes the shape of the nozzle 21, such as an attachment that widens the cross-sectional area of the duct, is installed at the nozzle 21 of the duct 2. Further, for example, an attachment for changing the direction of the air outlet of the duct is attached to the nozzle 21 of the duct 2, so that the orientation of the nozzle 21 is changed to a certain extent, so that it can be blown in a wider direction, thereby improving work efficiency. In this embodiment, the air duct is a straight tube that extends straight, and the end portion has no portion where the diameter of the tube changes. Of course, it is also possible to arrange the portion where the pipe diameter changes at the end of the air duct or the entire air duct to facilitate the adjustment of the air outlet speed. For example, a tapered structure having a radius gradient can be provided on the duct 2. In a preferred embodiment, as shown in Figures 23 and 24, the duct 2 is generally a conical tube. One end of the duct 2 has a large cross-sectional area, and the other end has a relatively small cross-sectional area. Further, for example, a bent portion may be provided in the air duct 2 so that the extending direction of the air duct 2 is turned at the bent portion. In a preferred embodiment, the bend is disposed adjacent the spout 21 of the duct 2. Further, in order to reduce the pressure of the grip, a roller supported on the ground is provided near the bent portion of the duct 2. Thus, when the suction function is performed, the weight of the duct 2 is effectively shunted by the roller support. The length of the duct 2 ranges from 500 mm to 800 mm, preferably around 550 mm, for safety requirements. The cross-sectional area of the duct 2 ranges from 5,000 square millimeters to 15,000 square millimeters, preferably around 8,000 square millimeters. As shown in FIG. 4 and FIG. 5, one end of the air duct 2 has a connection port 25 connecting the main body 10, and the other end is provided with an external connection. Nozzle 21. In the embodiment of Fig. 1, the connecting port 25 of the duct 2 connecting the main body 10 has a small cross-sectional area, preferably 100 mm in diameter, and the nozzle 21 of the duct 2 has a large cross-sectional area, preferably Its diameter is 110 mm. Therefore, the cross-sectional area of the connection port 25 is smaller than the cross-sectional area of the nozzle port 21. When the duct 2 is connected to the body 10, the nozzle 21 of the duct 2 and the first opening 12 likewise at least partially coincide with a projection on a plane perpendicular to the fan axis 39. The cross section formed by the nozzle 21 is substantially at an angle to the horizontal line. When the handle portion 9 located at the longitudinal rear end of the air suction device 1 is held by the user, the position where the user's hand is naturally lowered is not close to the ground, but is about several tens of centimeters to one meter from the ground. The nozzle 21 of the air duct 2 located at the longitudinal front end of the air suction device 1 has a certain angle with the horizontal line, so that the nozzle 21 can be relatively close to the ground. The duct 2 can be detachably connected to the interface 11, or can be fixedly connected at all times. In the present embodiment, the air duct 2 is connected to the main body 10 through the interface 11 in either the blow mode or the suction mode, and does not need to be switched in different modes, so the duct 2 can be fixedly connected to the main body 10. The duct 2 and the main body 10 are separated at the time of transportation or storage to reduce the occupied volume. The nozzle 21 of the duct 2 is also referred to as a second opening, the second opening being relative to the first opening 12 of the outer casing 14. Therefore, in the present embodiment, the main body 10 has only one interface 11 connected to the duct 2.
如图2所示，吹吸装置1还包括安全机构8。安全机构8的作用是确保风管2连接到主体10后启动电路才会导通，用户操作控制开关91才能起作用。当风管2未连接到主体10时，安全机构8使启动电路断开，用户即使操作控制开关91也无法使马达4正常工作，从而确保了安全性。在本实施例中，安全机构8靠近主体10的接口11设置。安全机构8包括触发杆81和抵接触发杆81的触发开关82。触发开关82上设有触发钮83，触发杆81的一端抵接触发钮83。而触发杆81的另一端为自由端。当风管2安装连接接口11时，安全机构8被触发。具体地，风管2抵接触发杆81的自由端，从而通过触发杆81挤压触发钮83，使得电路导通，使得控制开关91得以控制。当风管2从接口11上拆卸下来时，触发钮83复位使得电路断开。As shown in FIG. 2, the suction device 1 further includes a safety mechanism 8. The function of the safety mechanism 8 is to ensure that the starting circuit is turned on after the air duct 2 is connected to the main body 10, and the user operates the control switch 91 to function. When the air duct 2 is not connected to the main body 10, the safety mechanism 8 causes the start-up circuit to be disconnected, and the user cannot operate the motor 4 even if the control switch 91 is operated, thereby ensuring safety. In the present embodiment, the safety mechanism 8 is disposed adjacent to the interface 11 of the main body 10. The safety mechanism 8 includes a trigger lever 81 and a trigger switch 82 that abuts the contact lever 81. A trigger button 83 is disposed on the trigger switch 82, and one end of the trigger lever 81 abuts against the knob 83. The other end of the trigger lever 81 is a free end. When the duct 2 is fitted with the connection interface 11, the safety mechanism 8 is triggered. Specifically, the air duct 2 abuts against the free end of the hair rod 81, so that the trigger button 83 is pressed by the trigger lever 81, so that the circuit is turned on, so that the control switch 91 is controlled. When the duct 2 is detached from the interface 11, the trigger button 83 is reset to cause the circuit to be disconnected.
第一开口12设置于主体10的纵向后端。在如图17所示的实施例中，第一开口12具有可拆卸的安全护罩121。在优选的实施例中，安全护罩121可围绕一转轴转动从而打开或关闭第一开口12。在其他的实施例中，安全护罩121也可以卡扣方式或者插拔方式固定第一开口12上。另外，安全护罩121上设有若干网眼状的进气结构。空气可以从进气结构通过第一开口12，但是树枝树叶等 体积较大的颗粒物无法通过，而被挡在安全护罩121的外面。并且由于有安全护罩的阻挡作用，用户的手不会伸入第一开口12内部而造成伤害。在优选的实施例中，当安全护罩121打开第一开口12后，第一开口12可以连接收集装置。收集装置可以是一个可拆卸的连接吹吸装置1的附件。收集装置可以是布袋，用于收集在吸模式下被吸入树叶、树枝等异物。当然，在如图2所示的本实施例中，第一开口12并未设置安全护罩。第一开口12具有大致椭圆形的轮廓。形成的平面相对轴线41方向倾斜。倾斜角度大致为30～60度之间，优选地倾斜角度为45度。第一开口12的形状大致为椭圆形。如图8所示，风扇3的风扇轴线39延伸穿过第一开口12。在另外的实施例中，第一开口12也可以并非朝向纵向后端，而是外壳14部分设置弯曲部分，而第一开口12设置在弯曲部分上，从而使的位于弯曲部分的第一开口12朝向改变，不再朝向纵向后端。在一实施例中，弯曲部分向下弯曲，或者说朝向地面弯曲，从而使得第一开口12向下设置，也就是背离手柄部9的方向；在另一实施例中，弯曲部分可以向上弯曲，使得第一开口12向上设置，即靠近手柄部9的方向。The first opening 12 is provided at a longitudinal rear end of the body 10. In the embodiment shown in Figure 17, the first opening 12 has a detachable safety shield 121. In a preferred embodiment, the safety shield 121 is rotatable about a rotational axis to open or close the first opening 12. In other embodiments, the safety shield 121 can also be fastened to the first opening 12 by snapping or plugging. In addition, the safety shield 121 is provided with a plurality of mesh-shaped intake structures. Air can pass through the first opening 12 from the intake structure, but branches and leaves, etc. The bulky particles cannot pass through and are blocked outside the safety shield 121. And because of the blocking effect of the safety shield, the user's hand does not protrude into the interior of the first opening 12 and causes injury. In a preferred embodiment, the first opening 12 can be coupled to the collection device when the safety shield 121 opens the first opening 12. The collecting device can be a detachable attachment to the suction device 1. The collecting device may be a bag for collecting foreign matter such as leaves, branches, and the like that are sucked in the suction mode. Of course, in the embodiment shown in FIG. 2, the first opening 12 is not provided with a safety shield. The first opening 12 has a generally elliptical profile. The formed plane is inclined with respect to the direction of the axis 41. The angle of inclination is approximately between 30 and 60 degrees, preferably at an angle of 45 degrees. The shape of the first opening 12 is substantially elliptical. As shown in FIG. 8, the fan axis 39 of the fan 3 extends through the first opening 12. In other embodiments, the first opening 12 may not be oriented toward the longitudinal rear end, but the outer casing 14 is partially provided with a curved portion, and the first opening 12 is disposed on the curved portion such that the first opening 12 is located at the curved portion. The orientation changes and no longer faces the longitudinal rear end. In an embodiment, the curved portion is bent downward, or curved toward the ground, such that the first opening 12 is disposed downward, that is, a direction away from the handle portion 9; in another embodiment, the curved portion can be bent upward. The first opening 12 is placed upward, that is, in the direction of the handle portion 9.
而接口11设置在主体10的纵向前端。接口11用于与风管2连接。具体地，接口11与风管2的连接口25连接。主体10上的接口11有且仅有一个，因此无论是在吹模式还是吸模式下，风管2均连接于该接口11。接口11的形状与风管2的连接口25基本匹配。在本实施例中，接口11朝向纵向前端设置，而第一开口12朝向纵向后端设置，因此接口11与第一开口12的开口朝向相反。并且接口11与第一开口12位于气流产生装置的相对两侧。对于主体10而言，当吹吸装置1处于吹模式下，如图4所示，空气从第一开口12进入主体，然后基本沿直线方向移动，并从接口11离开主体10，并相应进入风管2。而在吸模式下，空气从接口11进入主体10，然后沿直线方向从第一开口12离开主体10。因此在吹模式和吸模式下，气流产生装置产生的气流在接口11与第一开口12之间的移动方向相反。另外，值得注意的是，在本实施例中，风扇3的风扇轴线39延伸穿过接口11。对于气流产生装置的风扇3和马达4而言，马达4位于风扇3与第一开口12之间，使得马达4到第一开口12的距离小于风扇3到第一开口12的距离。在本实施例中，风扇3、马达4和第一开口12依次沿直线排列设置。接口11和第一开口12沿风扇轴线39的延伸方向分别位于风扇3 的两侧。或者说，接口11和第一开口12位于气流产生装置的相对两侧。接口11与第一开口12在垂直于风扇轴线39的平面上的投影至少部分重合。因此，接口11、风扇3、马达4与第一开口12依次沿直线排列设置。The interface 11 is disposed at the longitudinal front end of the main body 10. The interface 11 is for connection to the duct 2. Specifically, the interface 11 is connected to the connection port 25 of the air duct 2. There is one and only one interface 11 on the main body 10, so the duct 2 is connected to the interface 11 whether in the blowing mode or the suction mode. The shape of the interface 11 substantially matches the connection opening 25 of the duct 2. In the present embodiment, the interface 11 is disposed toward the longitudinal front end, and the first opening 12 is disposed toward the longitudinal rear end, so that the opening of the interface 11 and the first opening 12 are opposite. And the interface 11 and the first opening 12 are located on opposite sides of the airflow generating device. For the main body 10, when the air suction device 1 is in the blowing mode, as shown in Fig. 4, air enters the main body from the first opening 12, then moves substantially in a linear direction, and leaves the main body 10 from the interface 11, and enters the wind accordingly. Tube 2. While in the suction mode, air enters the body 10 from the interface 11 and then exits the body 10 from the first opening 12 in a linear direction. Therefore, in the blow mode and the suction mode, the airflow generated by the airflow generating device is opposite in the direction of movement between the interface 11 and the first opening 12. Additionally, it is worth noting that in the present embodiment, the fan axis 39 of the fan 3 extends through the interface 11. For the fan 3 and the motor 4 of the airflow generating device, the motor 4 is located between the fan 3 and the first opening 12 such that the distance of the motor 4 from the first opening 12 is smaller than the distance of the fan 3 to the first opening 12. In the present embodiment, the fan 3, the motor 4, and the first opening 12 are sequentially arranged in a line. The interface 11 and the first opening 12 are respectively located in the fan 3 along the extending direction of the fan axis 39 On both sides. Alternatively, the interface 11 and the first opening 12 are located on opposite sides of the airflow generating device. The projection of the interface 11 with the first opening 12 in a plane perpendicular to the fan axis 39 at least partially coincides. Therefore, the interface 11, the fan 3, the motor 4, and the first opening 12 are sequentially arranged in a line.
当风管2连接到主体10后，在吹模式下，气流产生装置产生沿一方向移动的气流，空气从主体10的第一开口12进入外壳14，然后在主体10内移动直至形成从风管2的管口21吹出的气流，气流的移动方向如图4中单线箭头所示。而在吸模式下，风管2仍然连接主体10，并且连接主体10的位置并没有变化。气流产生装置产生沿另一方向移动的气流，在此模式下气流的移动方向与在吹模式下气流移动的方向不同，空气从管口21进入风管2。气流吸入后在主体10内移动，并最终形成从第一开口12排出的气流，如图5中单线箭头所示。当然另外强调的是，在吸模式下，由于管口21对准地面，树叶、树枝、灰尘等异物会随气流一同通过管口21进入主体10内。而在吹模式下，第一开口12远离地面，因此仅仅空气会进入主体10。因此，如图6所示，在吹吸装置1内部，第一开口12与管口21之间形成供气体流动的气流通道55，换句话说，外壳14和风管2共同形成供气流移动的气流通道55。该气流通道55是气体在吹吸装置1内移动经过的通路。在通常的情况下，由于吹吸装置1具有不同的工作模式吹模式和吸模式，出于各自表现性能的考虑，在不同的工作模式下气流通道是不同的。而在本发明中，气流通道55是气流在吹模式和吸模式下共同使用的通道。也就是说，在吹模式和吸模式下，气流都在该同一个气流通道中移动。只不过是在两种模式下，气流移动的方向是不相同的。最优的，两种模式下气流移动的方向是相反的。具体地，在吹模式下，气流从第一开口12向管口21移动。而在吸模式下，气流从管口21向第一开口12移动。另外，值得注意的是，气流通道55整体上沿纵向延伸，当然气流通道55也可以产生部分的弯曲或者弯折。在本实施例中，风扇3和马达4均位于气流通道55中。当处于吹模式时，风扇3受到马达4的驱动而旋转，风扇3围绕风扇轴线39沿顺时针方向旋转，当切换到吸模式时，风扇3受到马达4的驱动而旋转，风扇3围绕风扇轴线39沿逆时针方向旋转。而在图20所示的实施例中，风扇3仍然位于气流通道55中，马达4并非位于气流通道55中。When the duct 2 is connected to the main body 10, in the blowing mode, the airflow generating means generates a flow of air moving in one direction, the air entering the outer casing 14 from the first opening 12 of the main body 10, and then moving within the main body 10 until the air duct is formed The airflow blown by the nozzle 21 of 2, the moving direction of the airflow is as shown by the single-line arrow in FIG. While in the suction mode, the duct 2 is still connected to the main body 10, and the position of the connecting body 10 does not change. The airflow generating means generates a flow of air moving in the other direction. In this mode, the direction of movement of the airflow is different from the direction in which the airflow moves in the blow mode, and air enters the duct 2 from the nozzle 21. The airflow moves within the body 10 after inhalation and eventually forms an airflow exiting the first opening 12, as indicated by the single-line arrow in FIG. Of course, it is additionally emphasized that in the suction mode, since the nozzle 21 is aligned with the ground, foreign matter such as leaves, branches, dust, and the like may enter the body 10 through the nozzle 21 along with the airflow. In the blow mode, the first opening 12 is remote from the ground so that only air can enter the body 10. Therefore, as shown in FIG. 6, inside the air suction device 1, an air flow passage 55 for gas flow is formed between the first opening 12 and the nozzle 21, in other words, the outer casing 14 and the air duct 2 together form a flow for the airflow. Air flow passage 55. The air flow passage 55 is a passage through which the gas moves in the air suction device 1. In the usual case, since the blowing device 1 has different operating mode blowing modes and suction modes, the airflow passages are different in different operating modes for the respective performance performance considerations. In the present invention, however, the air flow path 55 is a passage in which the air flow is commonly used in the blow mode and the suction mode. That is to say, in the blowing mode and the suction mode, the airflow moves in the same airflow passage. It is only in two modes that the direction of airflow movement is different. Optimally, the direction of airflow movement is reversed in both modes. Specifically, in the blowing mode, the airflow moves from the first opening 12 to the nozzle 21. In the suction mode, the air flow moves from the nozzle 21 toward the first opening 12. In addition, it is worth noting that the air flow passage 55 extends in the longitudinal direction as a whole, and of course the air flow passage 55 may also partially bend or bend. In the present embodiment, both the fan 3 and the motor 4 are located in the air flow passage 55. When in the blowing mode, the fan 3 is rotated by the driving of the motor 4, and the fan 3 rotates clockwise around the fan axis 39. When switching to the suction mode, the fan 3 is rotated by the driving of the motor 4, and the fan 3 surrounds the fan axis. 39 rotates counterclockwise. In the embodiment shown in FIG. 20, the fan 3 is still located in the air flow passage 55, and the motor 4 is not located in the air flow passage 55.
如图7和图8所示，吹吸装置1还包括涵道5。涵道5的作用引导风扇3 产生的气流向风管2移动，从而使气流移动的方向更加一致，提升了整个气流的效果。在本实施例中，涵道5同样位于气流通道55内，并且位于接口11与风扇3之间。涵道5靠近主体10的接口11设置，并且涵道5相较于风扇3更靠近纵向前端，或者说涵道5位于风扇3远离第一开口12的一侧。当风扇3产生向接口11移动的气流，气流会先通过涵道5再到达接口11。换句话说，气流在达到接口11前会先通过涵道5的导流。涵道5包括了位于外壳14内部的导流体51、固定连接导流体51的静叶片52和用于收纳导流体51与静叶片52的导流罩53。导流罩53位于外壳14的内部，并且导流罩53与外壳14之间形成空间。在本实施例中，导流罩53为内部中空的圆筒形壳体，圆筒形壳体内部容纳导流体51和静叶片52。风扇3产生的气流从导流罩53的内部通过。导流罩53优选的还设有突起的固定元件54。固定元件54设置位于导流罩53的外侧，并能够与外壳14的内侧固定配接，从而起到固定导流罩53位置的作用。在本实施例中，固定元件54可以是突出表面的筋条，并且呈环状的设置。在另一实施例如图17所示，在导流罩53与外壳14之间还设有减振机构56，减振机构56用于减少从导流罩53传递给外壳14的振动。在导流罩53上设有定位槽57，减振机构56即收纳于该定位槽57中。而在外壳14的内壁相应位置处设置有配合定位槽57的定位台阶58。在本实施例中，减振机构56是环形围绕导流罩53的弹性圈。当然，减振机构56也可以是块状的弹性块。另外设置注意的是，减振机构56优选地位于导流罩53的纵向前端。导流罩53还具有设置在纵向后端的配合部59。配合部59同样沿纵向延伸。配合部59具有半径渐变的锥形结构，锥形结构类似朝向后端开口的喇叭口，其作用是为了部分贴合包裹马达4的马达罩44。马达罩44能够部分地与配合部59配合固定。导流罩53沿纵向延伸，其纵向两端均不封闭。当然在其他实施例中，外壳14也可以作为导流罩53。As shown in FIGS. 7 and 8, the suction device 1 further includes a duct 5 . The role of the duct 5 guides the fan 3 The generated airflow moves toward the duct 2, thereby making the direction of the airflow more uniform, improving the effect of the entire airflow. In the present embodiment, the duct 5 is also located in the air flow passage 55 and is located between the interface 11 and the fan 3. The duct 5 is disposed near the interface 11 of the main body 10, and the duct 5 is closer to the longitudinal front end than the fan 3, or the duct 5 is located on the side of the fan 3 remote from the first opening 12. When the fan 3 produces a flow of air moving toward the interface 11, the airflow will first pass through the duct 5 to the interface 11. In other words, the airflow will first pass through the duct 5 before it reaches the interface 11. The duct 5 includes a fluid guide 51 located inside the outer casing 14, a stationary vane 52 fixedly connected to the fluid guide 51, and a shroud 53 for receiving the fluid guide 51 and the stationary vane 52. The shroud 53 is located inside the outer casing 14, and a space is formed between the shroud 53 and the outer casing 14. In the present embodiment, the shroud 53 is an inner hollow cylindrical casing that houses the fluid guiding body 51 and the stationary vanes 52. The airflow generated by the fan 3 passes through the inside of the shroud 53. The shroud 53 is preferably also provided with a raised fixing element 54. The fixing member 54 is disposed outside the shroud 53 and can be fixedly coupled to the inner side of the outer casing 14 to function to fix the position of the shroud 53. In the present embodiment, the fixing member 54 may be a rib that protrudes from the surface and is provided in an annular shape. In another embodiment, as shown in FIG. 17, a damper mechanism 56 is further provided between the shroud 53 and the outer casing 14, and the damper mechanism 56 serves to reduce vibration transmitted from the shroud 53 to the outer casing 14. The guide cover 53 is provided with a positioning groove 57, and the damper mechanism 56 is housed in the positioning groove 57. A positioning step 58 that fits the positioning groove 57 is provided at a corresponding position on the inner wall of the outer casing 14. In the present embodiment, the damper mechanism 56 is an elastic ring that surrounds the shroud 53 in a ring shape. Of course, the damper mechanism 56 can also be a block-shaped elastic block. In addition, it is noted that the damper mechanism 56 is preferably located at the longitudinal front end of the shroud 53. The shroud 53 also has a mating portion 59 disposed at the longitudinal rear end. The fitting portion 59 also extends in the longitudinal direction. The mating portion 59 has a tapered structure having a tapered shape, and the tapered structure is similar to the flared opening toward the rear end, and functions to partially fit the motor cover 44 that wraps the motor 4. The motor cover 44 can be partially fixedly coupled to the mating portion 59. The shroud 53 extends in the longitudinal direction and is not closed at both longitudinal ends. Of course, in other embodiments, the outer casing 14 can also function as a shroud 53.
导流体51位于导流罩53中。导流体51整体大致沿轴线41方向延伸，并呈锥形结构，其一端朝向接口11；而另一端背向接口11，背向接口11的该端具有开口。导流体51的延伸方向与导流罩53的延伸方向一致。导流体51具有中空的内部，其他元件可以通过该开口进入到导流体51的内部。风扇3产生的气流从导流体51的外侧通过。因此，导流体51与导流罩53配合使得风扇3 产生的气流在导流体51和导流罩53之间通过。The fluid guide 51 is located in the shroud 53. The fluid guiding body 51 extends substantially in the direction of the axis 41 and has a tapered structure with one end facing the interface 11 and the other end facing away from the interface 11, and the end facing away from the interface 11 has an opening. The extending direction of the fluid guide 51 coincides with the extending direction of the shroud 53. The fluid guide 51 has a hollow interior through which other elements can enter the interior of the fluid guide 51. The airflow generated by the fan 3 passes through the outside of the fluid guide 51. Therefore, the fluid guide 51 cooperates with the shroud 53 such that the fan 3 The generated gas flow passes between the flow guide 51 and the shroud 53.
在导流体51的外部设有静叶片52。静叶片52优选地周向均匀地分布在导流体51上。静叶片52与导流体51固定连接。优选地，静叶片52形成的平面与轴线41的方向大致倾斜一定角度设置。倾斜角度可以设置为8度至15度之间。静叶片52的数量大致为7个。涵道5位于气流通道55中。导流罩53与导流体51之间的空间供气流穿过。而静叶片52设置在导流体51和导流罩53之间，恰好位于气流通道55之中，能够对通过的气流进行引导。由于在吹模式下，涵道5位于风扇3的下游区域，从风扇3吹出的气流通过涵道5时产生整流作用，从而可以调整部分气流的旋向，减少涡流的产生，使整体气流方向更齐整，提升气流的吹风效果和效率。值得注意的是，静叶片52和风扇3的叶片32都是围绕轴线周向设置。为了避免两者在周向上的相互干扰，确保其在周向的任意相位上不会有叶片的较多重合而产生类似的共振叠加效应，使得静叶片52和叶片32的数量设置互为质数。例如，静叶片52可以设置为6个，而叶片32的数量相应为11个。又例如静叶片52的数量7个，而叶片32的数量对应为12个。如此在风扇3进行转动工作的时候，在任意一时刻，叶片32和静叶片52在相位上重叠的数量至多为一。涵道5可以位于主体10内并与主体10一体成型固定，当然涵道5也可以作为一个独立的元件与主体10固定配接。而在另外的实施例中，涵道5也可以设置在风管2中。A stator blade 52 is provided outside the fluid guide 51. The stationary vanes 52 are preferably evenly distributed circumferentially on the fluid guide 51. The stationary vane 52 is fixedly coupled to the fluid guide 51. Preferably, the plane formed by the stationary vanes 52 is disposed at an oblique angle to the direction of the axis 41. The tilt angle can be set between 8 and 15 degrees. The number of the stationary blades 52 is approximately seven. The duct 5 is located in the air flow passage 55. A space between the shroud 53 and the fluid guide 51 is supplied through the airflow. The stationary vane 52 is disposed between the fluid guide 51 and the shroud 53, just in the air flow passage 55, and is capable of guiding the passing airflow. Since the duct 5 is located in the downstream area of the fan 3 in the blowing mode, the airflow blown from the fan 3 is rectified when passing through the duct 5, so that the direction of the partial airflow can be adjusted, the generation of the eddy current can be reduced, and the overall airflow direction can be further improved. Tightening, improving the air blowing effect and efficiency of the airflow. It is worth noting that both the stationary vanes 52 and the vanes 32 of the fan 3 are circumferentially disposed about the axis. In order to avoid mutual interference between the two in the circumferential direction, it is ensured that there is no more overlap of the blades in any phase in the circumferential direction to produce a similar resonance superposition effect, so that the number of the stationary blades 52 and the blades 32 are set to be prime numbers. For example, the stationary blades 52 may be set to six, and the number of the blades 32 is correspondingly eleven. For another example, the number of the stationary blades 52 is seven, and the number of the blades 32 corresponds to twelve. Thus, at any moment when the fan 3 performs the turning operation, the number of the blades 32 and the stationary blades 52 overlapping in phase is at most one. The duct 5 can be located in the main body 10 and integrally formed with the main body 10. Of course, the duct 5 can also be fixedly coupled to the main body 10 as a separate component. In other embodiments, the duct 5 can also be disposed in the duct 2.
如图4和图5所示，吹吸装置1具有至少两种工作模式:吹模式和吸模式。当吹吸装置1处于吹模式时，风扇3可操作地沿第一方向旋转，使得产生的气流从风管2的管口21吹出。当吹吸装置1处于吸模式时，风扇3可操作地沿第二方向旋转，使得产生的气流从风管2的管口21吸入。值得注意的是，无论处于吹模式还是吸模式，风管2都与主体10的接口11连接。这样在吹吸装置1从吹模式切换到吸模式时，或者从吸模式切换到吹模式时，用户都无需对风管2的位置及固定进行额外的操作或移动。只需要对风扇3的旋转方向进行控制即可。当切换到吹模式时，控制风扇3沿第一方向旋转。当切换到吸模式时，控制风扇3沿第二方向旋转。进一步地，在吹模式下，空气从第一开口12进入并从管口21吹出。而在吸模式下，空气从管口21吸入并从第一开口12排出。进入无论是吹模式还是吸模式，空气通过的路径都是位于第一开口12和管口 21之间，而且移动通过的路径是相同的。只是吹模式下和吸模式下空气移动的方向不同。因此在吹模式或吸模式下吹吸装置1都共用该气流通道55。由此进一步简化吹吸装置1的气流通道的结构，不必需要额外设置第二气流通道。As shown in Figures 4 and 5, the suction device 1 has at least two modes of operation: a blow mode and a suction mode. When the blowing device 1 is in the blowing mode, the fan 3 is operatively rotated in the first direction such that the generated airflow is blown from the nozzle 21 of the duct 2. When the suction device 1 is in the suction mode, the fan 3 is operatively rotated in the second direction such that the generated airflow is drawn from the nozzle 21 of the duct 2. It is to be noted that the duct 2 is connected to the interface 11 of the main body 10 regardless of whether it is in the blow mode or the suction mode. Thus, when the suction device 1 is switched from the blowing mode to the suction mode, or when switching from the suction mode to the blowing mode, the user does not need to perform additional operations or movements on the position and fixation of the air duct 2. It is only necessary to control the direction of rotation of the fan 3. When switching to the blow mode, the fan 3 is controlled to rotate in the first direction. When switching to the suction mode, the fan 3 is controlled to rotate in the second direction. Further, in the blowing mode, air enters from the first opening 12 and is blown out from the nozzle 21. In the suction mode, air is drawn in from the nozzle 21 and discharged from the first opening 12. Entering either the blow mode or the suction mode, the path through which the air passes is located at the first opening 12 and the nozzle Between 21, and the path through which the movement passes is the same. It is only the direction in which the air moves in the blow mode and the suction mode. Therefore, the air blowing passages 1 are shared by the air suction device 1 in the blowing mode or the suction mode. This further simplifies the structure of the air flow passage of the air suction device 1, without the need to additionally provide a second air flow passage.
另外，由于吹吸装置1具有至少两种不同的工作模式，因此必须考虑如何操作方便的切换工作模式。因此吹吸装置1具有吹吸模式转换开关，用户操作吹吸模式转换开关即可进行模式切换，例如从第一工作模式切换到第二工作模式，或者从第二工作模式切换到第一工作模式。在本发明中，风管2在切换模式时不需要移动或者改变位置，因此吹吸模式转换开关可以是控制开关91。当操作控制开关91切换至使风扇3沿第一方向旋转的位置，吹吸装置1即处于吹模式。当操作控制开关91切换至使风扇3沿第二方向旋转的位置，吹吸装置1即处于吸模式。由此带来的好处是切换工作模式时用户操作极为方便，而且不需要更换风管2或者移动风管2。当吹吸装置1不需要使用时，风管2可以与主体10拆卸下来，便于存储。当吹吸装置1需要使用时，无论是吹模式还是吸模式，只需要把风管2安装到主体10上，然后操作控制开关91，使得马达4启动并沿相应的方向旋转。具体地，当吹吸装置1处于吹模式时，操作控制开关91移动至第一操作位置，当吹吸装置1处于吸模式时，操作控制开关91移动至第二操作位置。即使需要进行模式切换，风管2也无需频繁的拆装。而且，由于吹吸装置1的风扇3包含了轴流风扇，由于轴流风扇能够产生较高的风速，相较于传统的离心风扇，在没有增加尺寸的前提下，吹风效率得到极大提高。由于马达4连接风扇3，当马达4沿顺时针方向旋转时，马达4就会带动风扇3沿顺时针方向旋转；而当马达4沿逆时针方向旋转时，马达4就会带动风扇3沿逆时针方向旋转。因此在本实施例中，控制开关91以控制马达4旋转方向的形式间接实现对风扇3的控制。如图29至图31所示，马达4包括了定子40和可相对定子40旋转的转子49。定子40和转子49分别缠绕线圈并且接入电路，利用电磁感应的原理在电路导通后产生的电流即可实现定子40和转子49相对旋转。而控制开关91即用来控制电路的通断。控制开关91具有多个档位，或者说具有多个操作位置。各个档位或者操作位置之间可以操作地进行移动。在如图29所示的实施例中，控制开关91具有引脚102和引脚105，当控制开关91***作地移动至第一操作位置时，引脚102和引脚103导通的同时引脚 104和引导105导通，此时根据导通的电路，定子40所在电路的电流方向和转子49所在电路的电流方向是相同的，在电磁感应原理的作用下，转子49相对定子40沿顺时针方向旋转，则马达4整体表现为顺时针方向旋转，对应的风扇3也相应顺时针方向旋转，此时吹吸装置1处于吹模式。当需要切换吹吸装置1的模式时，只需要操作控制开关91移动至第二操作位置，如图30所示，引脚2和引脚1导通同时引脚6和引脚5导通，此时定子40所在电路的电流方向产生了改变，而转子49所在电路的电流方向并没有变化，因而转子49相对定子40沿逆时针方向旋转，马达4和风扇3均相应沿逆时针方向旋转，此时吹吸装置1处于吸模式。当然，对于本领域技术人员容易想到的是，在控制开关91移动至不同的操作位置的时候，使经过定子40的电流不变，而使转子49的电流方向改变。总之，在控制开关91移动至不同位置时，使经过转子49和定子40其中之一的电流方向产生改变即可。因此控制吹吸装置切换吹吸模式的方法是操作控制开关91从使轴流风扇第一方向旋转的第一操作位置移动到使轴流风扇沿第二方向旋转的第二操作位置。而在切换过程中，风管2连接主体10的位置保持不变。在优选的实施例中，控制开关91还可以具有不同于第一、第二操作位置的第三操作位置。在该操作位置，如图31所示，引脚102和引脚105并没有与其他引脚连接，因此连接定子40和转子49的电路并没有导通，也就是说，马达4并不会转动，处在停机的状态。因此控制开关91可以控制马达4在三种状态之间进行切换，分别是正转状态、停机状态和反转状态。另外，如图29至图31所示，在定子40或/和转子49所在的电路上还可以设置联动安全机构8的安全开关84。当安全开关84未被触发时，无论控制开关91处于哪个操作位置，整个电路都处在断路状态，马达4始终不会启动。只有当安全开关84被触发时，控制开关91才能发挥控制电路的作用。In addition, since the blowing device 1 has at least two different operating modes, it is necessary to consider how to conveniently switch the operating mode. Therefore, the air suction device 1 has a blow mode switching switch, and the user can perform mode switching by operating the blow mode switch, for example, switching from the first working mode to the second working mode, or switching from the second working mode to the first working mode. . In the present invention, the duct 2 does not need to be moved or changed in position when switching modes, and therefore the blow mode changeover switch can be the control switch 91. When the operation control switch 91 is switched to a position where the fan 3 is rotated in the first direction, the suction device 1 is in the blowing mode. When the operation control switch 91 is switched to a position where the fan 3 is rotated in the second direction, the suction device 1 is in the suction mode. The resulting benefit is that the user's operation is extremely convenient when switching the operating mode, and there is no need to replace the duct 2 or move the duct 2. When the suction device 1 is not required to be used, the air duct 2 can be detached from the main body 10 for storage. When the suction device 1 is required to be used, whether it is the blow mode or the suction mode, it is only necessary to mount the duct 2 to the main body 10, and then operate the control switch 91 so that the motor 4 is activated and rotated in the corresponding direction. Specifically, when the suction device 1 is in the blowing mode, the operation control switch 91 is moved to the first operation position, and when the suction device 1 is in the suction mode, the operation control switch 91 is moved to the second operation position. Even if mode switching is required, the duct 2 does not need to be disassembled frequently. Moreover, since the fan 3 of the air suction device 1 includes the axial flow fan, since the axial flow fan can generate a high wind speed, the air blowing efficiency is greatly improved without increasing the size compared with the conventional centrifugal fan. Since the motor 4 is connected to the fan 3, when the motor 4 rotates in the clockwise direction, the motor 4 drives the fan 3 to rotate in the clockwise direction; and when the motor 4 rotates in the counterclockwise direction, the motor 4 drives the fan 3 along the counter. Rotate in the hour hand direction. Therefore, in the present embodiment, the control switch 91 indirectly controls the fan 3 in the form of controlling the direction of rotation of the motor 4. As shown in FIGS. 29 to 31, the motor 4 includes a stator 40 and a rotor 49 rotatable relative to the stator 40. The stator 40 and the rotor 49 are respectively wound around the coil and connected to the circuit, and the relative rotation of the stator 40 and the rotor 49 can be realized by the current generated after the circuit is turned on by the principle of electromagnetic induction. The control switch 91 is used to control the on and off of the circuit. The control switch 91 has a plurality of gear positions or has a plurality of operating positions. The various gear positions or operating positions are operatively movable. In the embodiment shown in FIG. 29, the control switch 91 has a pin 102 and a pin 105. When the control switch 91 is operatively moved to the first operational position, the pin 102 and the pin 103 are turned on simultaneously. Foot 104 and the guide 105 are turned on. At this time, according to the turned-on circuit, the current direction of the circuit where the stator 40 is located and the current direction of the circuit where the rotor 49 is located are the same. Under the action of the electromagnetic induction principle, the rotor 49 is clockwise with respect to the stator 40. When the direction is rotated, the motor 4 as a whole rotates in a clockwise direction, and the corresponding fan 3 also rotates clockwise, and the suction device 1 is in the blowing mode. When it is necessary to switch the mode of the suction device 1, only the operation control switch 91 needs to be moved to the second operation position. As shown in FIG. 30, the pin 2 and the pin 1 are turned on while the pin 6 and the pin 5 are turned on. At this time, the current direction of the circuit where the stator 40 is located is changed, and the current direction of the circuit where the rotor 49 is located does not change, so that the rotor 49 rotates counterclockwise with respect to the stator 40, and the motor 4 and the fan 3 both rotate counterclockwise accordingly. At this time, the suction device 1 is in the suction mode. Of course, it will be readily apparent to those skilled in the art that when the control switch 91 is moved to a different operational position, the current through the stator 40 is made constant and the direction of current flow of the rotor 49 is changed. In summary, when the control switch 91 is moved to a different position, the direction of the current passing through one of the rotor 49 and the stator 40 may be changed. Therefore, the method of controlling the blowing means to switch the blowing mode is to operate the control switch 91 from a first operating position in which the axial fan is rotated in the first direction to a second operating position in which the axial fan is rotated in the second direction. During the switching process, the position of the duct 2 connected to the main body 10 remains unchanged. In a preferred embodiment, the control switch 91 can also have a third operational position that is different from the first, second operational positions. In this operational position, as shown in FIG. 31, the pin 102 and the pin 105 are not connected to other pins, so the circuit connecting the stator 40 and the rotor 49 is not turned on, that is, the motor 4 does not rotate. , in the state of shutdown. Therefore, the control switch 91 can control the motor 4 to switch between three states, a forward rotation state, a shutdown state, and an inversion state, respectively. Further, as shown in FIGS. 29 to 31, a safety switch 84 of the interlocking safety mechanism 8 may be provided on the circuit in which the stator 40 or/and the rotor 49 is located. When the safety switch 84 is not activated, regardless of which operating position the control switch 91 is in, the entire circuit is in an open state and the motor 4 is never activated. Only when the safety switch 84 is triggered can the control switch 91 function as a control circuit.
另外，如图2、图6和图7所示，吹吸装置1还包括粉碎机构6。由于风扇3或/和马达4均位于气流通道55内，在吸模式下，树枝叶等体积较大的物体会随同空气从管口21进入到主体10，因此会对风扇3或/和马达4造成损害，影响吹吸装置1的使用寿命。因此设置粉碎机构6的目的是对体积较大的吸入物进行粉碎，转化成体积较小、重量较轻的物体经过风扇3，减少重量较大的物体高速撞击风扇3而造成风扇3的损坏。因此粉碎机构6设置在风扇3和管 口21之间的位置，在本实施例中，粉碎机构6设置在主体10内靠近接口11的位置，使得在吸模式下待粉碎物从管口21进入主体10后，先通过粉碎机构6再通过风扇3。在本实施例中，涵道5位于粉碎机构6与风扇3之间，风扇3和粉碎机构6分别位于涵道5的相对的各一侧，也就是说粉碎机构6比涵道5更靠近管口21。粉碎机构6、涵道5与风扇3依次沿直线排列设置。涵道5位于风扇3的远离第一开口12的一侧。粉碎机构6可被驱动的围绕一旋转轴线旋转而产生粉碎效果。在本实施例中，粉碎机构6可被马达4驱动而进行旋转。吹吸装置1包括了连接风扇3和粉碎机构6的传动机构7。传动机构7使得粉碎机构6作旋转运动。在本实施例中，粉碎机构6的旋转轴线与风扇3的转动轴线重合设置。当然，粉碎机构6的旋转轴线与风扇3的转动轴线也可以平行设置或者成一定锐角设置。由于本实施例中的风扇3也受马达4的驱动，因此马达4可同时驱动风扇3和粉碎机构6一起旋转。在优选的实施例中，风扇3和粉碎机构6可同步转动。风扇3沿第一方向旋转时，粉碎机构6同样沿第一方向旋转；风扇3沿第二方向旋转时，粉碎机构6相应沿第二方向旋转。当粉碎机构6转动时，粉碎机构6高速旋转形成大致垂直轴线41的切割平面，在吹模式下并不会影响空气流通；而在吸模式下，空气和待粉碎物都会通过该切割平面，其中，空气可以无损耗的通过该切割平面，而待粉碎物通过该切割平面时会被切割成细小物体，然后再通过风扇3，从而达到保护风扇3的目的，而且利于收集。如图2和图8所示，传动机构7为沿纵向延伸的传动轴71。传动轴71可围绕轴线41旋转，当然转动轴71也可以通过一些偏心结构使得传动轴71不围绕轴线41旋转。传动轴71的一端连接风扇3，另一端则连接粉碎机构6，从而使得风扇3与粉碎机构6一起同步运动。传动轴71连接风扇3的一端通过扁方或者花键等结构连接风扇3的连接孔33。由于马达轴42和传动轴71分别位于风扇3的两侧，因此马达4的马达轴42从连接孔33的一侧连接风扇3，而连接粉碎机构6的传动轴71从连接孔33的另一侧连接风扇3。在本实施例中，传动轴71与马达轴42并非直接连接，而是通过风扇3的传递实现两者的联动。而把粉碎机构6安装到传动轴71上后，传动轴71的该端还设有防滑结构74，防滑结构74的作用是防止粉碎机构6相对传动轴71轴向移动。在本实施例中，防滑结构74是可***传动轴71上的插孔的插销。另外，防滑结构 74还包括垫片等。由于马达4和粉碎机构6位于涵道5的相对两侧，因此传动轴71会穿过涵道5，从而把马达4与粉碎机构6连接起来。在本实施例中，传动轴71沿轴向穿过涵道5的导流体51中空的内部。如图6所示，在传动轴71和导流体51之间还设有用于支撑传动轴71的支撑轴承72。传动轴71能够相对支撑轴承72可旋转的支撑。支撑轴承72的数量可以是一个或多个。在本实施例中，支撑轴承72的数量为两个，且沿传动轴71的延伸方向间隔一定距离设置。而在其他实施例中，由于传动机构7可选择地切断风扇3传递给粉碎机构6的传动，如此当风扇3转动时，粉碎机构6可不转动。在该实施例中，传动机构7包括与马达轴42离合的离合器。当离合器可选择地与马达轴42动力连接时，风扇3与粉碎机构6一起转动，当离合器可选择地与马达轴42脱开动力连接时，风扇3仍然可以转动，而粉碎机构6则不转动。Further, as shown in FIGS. 2, 6, and 7, the suction device 1 further includes a pulverizing mechanism 6. Since the fan 3 or/and the motor 4 are both located in the air flow passage 55, in the suction mode, a bulky object such as a branch leaf will enter the main body 10 from the nozzle 21 along with the air, and thus the fan 3 or/and the motor 4 Causes damage and affects the service life of the suction device 1. Therefore, the purpose of the pulverizing mechanism 6 is to pulverize the inhaled body having a large volume, and convert it into a small-volume, light-weight object passing through the fan 3, thereby reducing the damage of the fan 3 caused by the high-weight object hitting the fan 3 at a high speed. Therefore the pulverizing mechanism 6 is disposed in the fan 3 and the tube In the present embodiment, the pulverizing mechanism 6 is disposed in the main body 10 at a position close to the interface 11, so that the object to be pulverized enters the main body 10 from the nozzle 21 in the suction mode, and then passes through the pulverizing mechanism 6 Pass the fan 3. In the present embodiment, the duct 5 is located between the pulverizing mechanism 6 and the fan 3, and the fan 3 and the pulverizing mechanism 6 are respectively located on opposite sides of the duct 5, that is, the pulverizing mechanism 6 is closer to the tube than the duct 5. Mouth 21. The pulverizing mechanism 6, the duct 5 and the fan 3 are sequentially arranged in a line. The duct 5 is located on the side of the fan 3 remote from the first opening 12. The pulverizing mechanism 6 can be driven to rotate about an axis of rotation to produce a pulverizing effect. In the present embodiment, the pulverizing mechanism 6 can be driven to rotate by the motor 4. The suction device 1 includes a transmission mechanism 7 that connects the fan 3 and the pulverizing mechanism 6. The transmission mechanism 7 causes the pulverizing mechanism 6 to perform a rotational motion. In the present embodiment, the rotation axis of the pulverizing mechanism 6 is disposed to coincide with the rotation axis of the fan 3. Of course, the axis of rotation of the pulverizing mechanism 6 and the axis of rotation of the fan 3 can also be arranged in parallel or at an acute angle. Since the fan 3 in this embodiment is also driven by the motor 4, the motor 4 can simultaneously drive the fan 3 and the pulverizing mechanism 6 to rotate together. In a preferred embodiment, the fan 3 and the comminuting mechanism 6 are rotatable in synchronism. When the fan 3 rotates in the first direction, the pulverizing mechanism 6 also rotates in the first direction; when the fan 3 rotates in the second direction, the pulverizing mechanism 6 rotates in the second direction. When the pulverizing mechanism 6 rotates, the pulverizing mechanism 6 rotates at a high speed to form a cutting plane of the substantially vertical axis 41, which does not affect the air circulation in the blowing mode; and in the suction mode, both the air and the object to be pulverized pass through the cutting plane, wherein The air can pass through the cutting plane without loss, and the object to be pulverized is cut into small objects when passing through the cutting plane, and then passes through the fan 3, thereby achieving the purpose of protecting the fan 3 and facilitating collection. As shown in Figures 2 and 8, the transmission mechanism 7 is a transmission shaft 71 extending in the longitudinal direction. The drive shaft 71 is rotatable about the axis 41. Of course, the rotational shaft 71 can also be rotated by the eccentric structure such that the drive shaft 71 does not rotate about the axis 41. One end of the transmission shaft 71 is connected to the fan 3, and the other end is connected to the pulverizing mechanism 6, so that the fan 3 and the pulverizing mechanism 6 move together. One end of the drive shaft 71 connected to the fan 3 is connected to the connection hole 33 of the fan 3 by a flat or spline structure. Since the motor shaft 42 and the transmission shaft 71 are respectively located at both sides of the fan 3, the motor shaft 42 of the motor 4 is connected to the fan 3 from one side of the connection hole 33, and the drive shaft 71 of the pulverizing mechanism 6 is connected from the other of the connection holes 33. Connect the fan 3 to the side. In the present embodiment, the transmission shaft 71 and the motor shaft 42 are not directly connected, but the linkage of the two is achieved by the transmission of the fan 3. After the pulverizing mechanism 6 is mounted on the transmission shaft 71, the end of the transmission shaft 71 is further provided with a non-slip structure 74, and the anti-slip structure 74 functions to prevent the pulverizing mechanism 6 from moving axially relative to the transmission shaft 71. In the present embodiment, the anti-slip structure 74 is a latch that can be inserted into a jack on the drive shaft 71. In addition, anti-skid structure 74 also includes gaskets and the like. Since the motor 4 and the pulverizing mechanism 6 are located on opposite sides of the duct 5, the transmission shaft 71 passes through the duct 5, thereby connecting the motor 4 to the pulverizing mechanism 6. In the present embodiment, the transmission shaft 71 passes axially through the hollow interior of the flow guiding body 51 of the duct 5. As shown in FIG. 6, a support bearing 72 for supporting the transmission shaft 71 is further provided between the transmission shaft 71 and the fluid guide 51. The drive shaft 71 is rotatably supported relative to the support bearing 72. The number of support bearings 72 may be one or more. In the present embodiment, the number of the support bearings 72 is two, and is disposed at a certain distance along the extending direction of the drive shaft 71. In other embodiments, since the transmission mechanism 7 selectively cuts off the transmission of the fan 3 to the pulverizing mechanism 6, the pulverizing mechanism 6 may not rotate when the fan 3 is rotated. In this embodiment, the transmission mechanism 7 includes a clutch that is coupled to the motor shaft 42. When the clutch is selectively operatively coupled to the motor shaft 42, the fan 3 rotates with the pulverizing mechanism 6, and when the clutch is selectively disengaged from the motor shaft 42, the fan 3 can still rotate, and the pulverizing mechanism 6 does not rotate. .
如图2和图7所示的实施例中，风扇3与涵道5位于马达4的同一侧，换句话说，马达4和涵道5分别位于风扇3的两侧。在该实施例中，传动轴71的一端并非直接连接马达轴42，而是连接风扇3。在本实施例中，风扇3的连接孔33为扁方形的通孔。该通孔分别以扁方形式连接传动轴71和马达轴42。尽管传动轴71和马达轴42并非直接连接，但是该两者通过分别与风扇3的配接，还是能够实现同步的运动。当然，还可以在连接孔33内设置花键结构，传动轴71和马达轴42分别通过各自花键配合连接风扇3。在其他实施例中，传动轴71和马达轴42也可以套接、行星齿轮、外啮合齿轮等常见传动形式直接配接。由于风扇3位于涵道5的纵向后侧，粉碎机构6位于涵道5的纵向前侧，传动轴71穿过涵道5的导流体51并连接粉碎机构6。当然，在其他的实施例中，马达4也可以位于涵道5中，即马达4和涵道5位于风扇3的同一侧。另外，由于粉碎机构6相较于涵道5更靠近纵向前端，为了不减少进入涵道5的空气量，粉碎机构6必须与涵道5之间保持一定的纵向间隔。其中，粉碎机构6与涵道5的静叶片52之间的最短距离为0.5～50mm。更优选地，粉碎机构6与涵道5的静叶片52之间的最短距离为10～20mm。进一步地，该最短距离为12mm或13mm。In the embodiment shown in Figures 2 and 7, the fan 3 and the duct 5 are located on the same side of the motor 4, in other words, the motor 4 and the duct 5 are located on both sides of the fan 3, respectively. In this embodiment, one end of the drive shaft 71 is not directly connected to the motor shaft 42, but is connected to the fan 3. In the present embodiment, the connecting hole 33 of the fan 3 is a flat through hole. The through holes are respectively connected to the drive shaft 71 and the motor shaft 42 in a flat form. Although the drive shaft 71 and the motor shaft 42 are not directly connected, the two can achieve synchronized motion by being respectively mated with the fan 3. Of course, it is also possible to provide a spline structure in the connecting hole 33, and the drive shaft 71 and the motor shaft 42 are respectively coupled to the fan 3 by respective spline engagement. In other embodiments, the drive shaft 71 and the motor shaft 42 can also be directly mated with conventional transmission forms such as sockets, planetary gears, and external gears. Since the fan 3 is located on the longitudinal rear side of the duct 5, the pulverizing mechanism 6 is located on the longitudinal front side of the duct 5, and the transmission shaft 71 passes through the flow guiding body 51 of the duct 5 and is connected to the pulverizing mechanism 6. Of course, in other embodiments, the motor 4 can also be located in the duct 5, ie the motor 4 and the duct 5 are located on the same side of the fan 3. Further, since the pulverizing mechanism 6 is closer to the longitudinal end than the duct 5, the pulverizing mechanism 6 must maintain a certain longitudinal interval with the duct 5 in order not to reduce the amount of air entering the duct 5. The shortest distance between the pulverizing mechanism 6 and the stationary vanes 52 of the duct 5 is 0.5 to 50 mm. More preferably, the shortest distance between the pulverizing mechanism 6 and the stationary vanes 52 of the duct 5 is 10 to 20 mm. Further, the shortest distance is 12 mm or 13 mm.
如图2所示的实施例中，粉碎机构6包括切割刀片。切割刀片由合金金属材料制成，具有一定的硬度，对高速通过的物体进行切割。该切割刀片可以围 绕粉碎机构6的旋转轴线转动。而在本实施例中，粉碎机构6的旋转轴线与轴线41重合。也可以把旋转轴线与轴线41设置成平行或者成一定角度相交。切割刀片沿垂直于旋转轴线的纵向延伸，其包括位于切割刀片中部的安装部61、沿安装部61的相反方向纵向延伸的两个工作部62，工作部62包括用于切割物体的切割部63。工作部62关于切割刀片的中心对称设置。安装部61用于与传动机构7连接，其包括安装孔64。安装孔64的形状可以是扁方形的，也可以具有花键结构或其他传动结构，以便与传动轴71动力连接。当然安装部61也可以采用多个形配的安装孔形式。另外，安装部61还包括把安装孔64固定在传动轴71上的定位件65。定位件65可以是常见的卡簧、销、螺母等。每个工作部62都包括位于切割刀片的纵向末端的端部67以及位于安装部61和端部67之间的侧边68。由于切割刀片的安装部61和端部67具有一定的纵向宽度，因此每个工作部62具有相对设置的两个侧边68，第一侧边681和第二侧边682。第一侧边681和第二侧边682均沿纵向延伸。切割部63位于其中一个侧边上，例如第一侧边681上。切割部63可以是刀刃也可以是锯齿，用于粉碎待粉碎物。切割部63当然可以设置成位于两个侧边68上。甚至位于端部67。在其中的一个实施例中，切割部63仅设置在第一侧边681上，切割刀片的第二侧边682相对第一侧边681呈卷曲设置。也就是说，切割刀片的第二侧边682沿纵向以及垂直纵向的横向上弯曲设置。从而使得第二侧边682能够形成空气提升部分，使得位于空气提升部分下游区域的空气负压降低，减少涡旋。当然在其他实施例中，切割刀片也可以整体基本呈平面设置，并没有形成卷曲。值得注意的是，粉碎机构6可以包含不止一个切割刀片，可以包括多个切割刀片。该多个切割刀片沿着粉碎机构6的轴线方向间隔一定距离的布置。在最佳的实施例中，粉碎机构6包括了两个沿轴线方向间隔设置的切割刀片。该两个切割刀片的结构是相同的，并且都受到马达4的驱动而具有一定相位差的同步转动。当然，切割刀片还可以具有不同的形状。在如图11所示的另外一个实施例中，切割刀片的每个工作部62的第一侧边681和第二侧边682相对倾斜设置，并且该两条侧边倾斜形成的夹角为一锐角，使得切割刀片从安装部61到端部67的纵向宽度逐渐变窄。这样设计的好处使切割刀片占据的空间减少，从而让出更多的空间使气流通过。在优选的实施例中，切割刀片在风管2的截面上的投影面积占到 整个风管2的截面面积比小于1/2时，气流的通过效果更佳。在更优选地实施例中，投影面积与截面面积之比为1/3或1/4。在图12所示的另一个实施例中，切割刀片的每个工作部62的第一侧边681和第二侧边682均呈弧形设置，并且该两条侧边的弧度不同，使得整个切割刀片大致呈S型。In the embodiment shown in Figure 2, the comminuting mechanism 6 comprises a cutting blade. The cutting blade is made of an alloy metal material and has a certain hardness to cut a high-speed object. The cutting blade can be surrounded Rotate around the axis of rotation of the pulverizing mechanism 6. In the present embodiment, however, the axis of rotation of the pulverizing mechanism 6 coincides with the axis 41. It is also possible to arrange the axis of rotation parallel to the axis 41 or at an angle. The cutting blade extends in a longitudinal direction perpendicular to the axis of rotation, comprising a mounting portion 61 located in the middle of the cutting blade, two working portions 62 extending longitudinally in opposite directions of the mounting portion 61, the working portion 62 including a cutting portion 63 for cutting an object . The working portion 62 is symmetrically disposed about the center of the cutting blade. The mounting portion 61 is for connection with the transmission mechanism 7, which includes a mounting hole 64. The mounting hole 64 may be rectangular in shape or may have a splined structure or other transmission structure for dynamic connection with the drive shaft 71. Of course, the mounting portion 61 can also take the form of a plurality of shaped mounting holes. In addition, the mounting portion 61 further includes a positioning member 65 that fixes the mounting hole 64 to the transmission shaft 71. The positioning member 65 can be a conventional snap spring, pin, nut, or the like. Each working portion 62 includes an end portion 67 at a longitudinal end of the cutting blade and a side edge 68 between the mounting portion 61 and the end portion 67. Since the mounting portion 61 and the end portion 67 of the cutting blade have a certain longitudinal width, each working portion 62 has opposite side edges 68, a first side 681 and a second side 682. Both the first side 681 and the second side 682 extend in the longitudinal direction. The cutting portion 63 is located on one of the sides, such as the first side 681. The cutting portion 63 may be a blade or a serration for pulverizing the object to be pulverized. The cutting portion 63 can of course be arranged to be situated on the two side edges 68. Even at the end 67. In one of the embodiments, the cutting portion 63 is disposed only on the first side 681, and the second side 682 of the cutting blade is crimped relative to the first side 681. That is, the second side 682 of the cutting blade is curved in the longitudinal direction as well as in the vertical direction. Thereby, the second side 682 can form an air lifting portion, so that the air negative pressure in the downstream region of the air lifting portion is lowered, reducing the vortex. Of course, in other embodiments, the cutting blades can also be disposed generally planar as a whole without forming a curl. It is worth noting that the comminuting mechanism 6 can comprise more than one cutting blade and can comprise a plurality of cutting blades. The plurality of cutting blades are arranged at a distance from each other along the axial direction of the pulverizing mechanism 6. In the preferred embodiment, the comminuting mechanism 6 includes two cutting blades spaced apart in the axial direction. The two cutting blades have the same structure and are driven by the motor 4 to have a certain phase difference of synchronous rotation. Of course, the cutting blades can also have different shapes. In another embodiment as shown in FIG. 11, the first side 681 and the second side 682 of each working portion 62 of the cutting blade are oppositely inclined, and the angle formed by the inclination of the two sides is one. The acute angle causes the cutting blade to gradually narrow from the longitudinal width of the mounting portion 61 to the end portion 67. The benefits of this design reduce the space occupied by the cutting blades, allowing more space for airflow. In a preferred embodiment, the projected area of the cutting blade on the cross section of the duct 2 is When the cross-sectional area ratio of the entire duct 2 is less than 1/2, the passage of the airflow is better. In a more preferred embodiment, the ratio of projected area to cross-sectional area is 1/3 or 1/4. In another embodiment shown in FIG. 12, the first side 681 and the second side 682 of each working portion 62 of the cutting blade are each arranged in an arc, and the curvature of the two sides is different, so that the whole The cutting blade is generally S-shaped.
在如图13和图14所示的实施例中，粉碎机构6还包括刀盘600以及设置在刀盘600上的刀片601。该粉碎机构6同样可以被马达4驱动而旋转。当然，粉碎机构6不被马达4驱动时停止旋转。刀盘600在本实施例中为圆盘形状。刀片601设置在圆盘的边缘。刀盘600的中央设有连接传动机构7的连接部602。传动机构7带动刀盘600围绕传动机构7的轴线旋转。当然旋转方向可以是沿一个方向的旋转也可以是沿正反两不同方向的旋转。在刀盘600的边缘设置若干个安装孔603，刀片601通过安装孔603与刀盘600配接。如图13所示，刀片601设有枢转柱604。枢转柱604穿过刀片601所在的平面，同时枢转柱604穿过安装孔603并可以与安装孔603的侧壁配合。安装孔603的面积大于安装柱604的截面积，当刀盘600受到传动机构7的驱动而做旋转运动时，位于刀盘600边缘的刀片601由于离心力作用而沿刀盘600的径向向外甩出。刀片601能够伸出刀盘600而进行切割。当刀片601遇到比较坚硬的物体时，刀片601与物体碰撞而使安装柱604在安装孔603内产生位移，从而使刀片601收回伸出刀盘600，如图13中的虚线所示，这样可以避免刀片601的磨损。在本实施例中，刀盘600上设有两组刀片601。当然刀盘600也可以设有多组刀片，例如3组、4组等。In the embodiment shown in Figures 13 and 14, the comminuting mechanism 6 further includes a cutter head 600 and a blade 601 disposed on the cutter head 600. The pulverizing mechanism 6 can also be driven to rotate by the motor 4. Of course, the pulverizing mechanism 6 stops rotating when it is not driven by the motor 4. The cutter head 600 is in the shape of a disk in this embodiment. The blade 601 is placed at the edge of the disc. A coupling portion 602 that connects the transmission mechanism 7 is provided at the center of the cutter head 600. The transmission mechanism 7 drives the cutter head 600 to rotate about the axis of the transmission mechanism 7. Of course, the direction of rotation may be a rotation in one direction or a rotation in two different directions. A plurality of mounting holes 603 are provided at the edge of the cutter head 600, and the blade 601 is mated with the cutter head 600 through the mounting holes 603. As shown in Figure 13, the blade 601 is provided with a pivot post 604. The pivot post 604 passes through the plane in which the blade 601 is located while the pivot post 604 passes through the mounting hole 603 and can mate with the sidewall of the mounting hole 603. The area of the mounting hole 603 is larger than the sectional area of the mounting post 604. When the cutter head 600 is rotated by the transmission mechanism 7, the blade 601 located at the edge of the cutter head 600 is radially outward of the cutter head 600 due to the centrifugal force. Pull out. The blade 601 is capable of extending the cutter head 600 for cutting. When the blade 601 encounters a relatively hard object, the blade 601 collides with the object to cause the mounting post 604 to be displaced within the mounting hole 603, thereby retracting the blade 601 out of the cutter head 600, as indicated by the dashed line in FIG. Wear of the blade 601 can be avoided. In the present embodiment, two sets of blades 601 are provided on the cutter head 600. Of course, the cutter head 600 can also be provided with a plurality of sets of blades, for example, 3 sets, 4 sets, and the like.
如图15和图16所示的另一实施例中，粉碎机构6包括至少一组对称设置的刀片601。当然，粉碎机构6也可以包括若干组刀片601，例如2组、3组甚至更多。另外粉碎机构6还包括伸缩件605。刀片601安装到伸缩件605上。如图15和图16所示，伸缩件605可带动刀片601在收缩状态和展开状态之间切换。如图15所示，刀片601向外张开，此时处于展开状态，刀片601张开时可以起到粉碎的作用。如图16所示，刀片601向内收缩，此时处于收缩状态。伸缩件605以可移动的方式带动刀片601张开或收缩。如图15和图16所示，伸缩件605可移动地连接传动机构7。传动机构7带动伸缩件605沿轴向移动。具体地，如图15所示，当传动机构7沿一方向转动时，伸缩件605受到该方向 的转动作用而朝纵向前端移动，此时刀片601处于展开状态。而对应的吹吸装置1正好处于吸模式状态下，展开的刀片601能够进行粉碎作用。如图16所示，当传动机构7沿另一方向转动时，伸缩件605受到作用而朝纵向后端移动，此时刀片601处于收缩状态。收缩的刀片601能够减少刀片601占据的横截面积，从而保证足够的空气流通面积。而对应的吹吸装置1正好处于吹模式状态下。也就是说，当吹吸装置1处于吸模式时，刀片601展开，从而进行粉碎。当吹吸装置1处于吹模式时，刀片601收缩，从而增加过风面积。In another embodiment, as shown in Figures 15 and 16, the shredder mechanism 6 includes at least one set of symmetrically disposed blades 601. Of course, the comminuting mechanism 6 can also comprise several sets of blades 601, for example 2 groups, 3 groups or even more. Further, the pulverizing mechanism 6 further includes a telescopic member 605. The blade 601 is mounted to the telescopic member 605. As shown in Figures 15 and 16, the telescoping member 605 can drive the blade 601 to switch between a collapsed state and an expanded state. As shown in Fig. 15, the blade 601 is flared outwardly, and is in an unfolded state at this time, and the blade 601 can function as a pulverization when it is opened. As shown in Fig. 16, the blade 601 is inwardly contracted and is now in a contracted state. The telescoping member 605 moves the blade 601 to open or contract in a movable manner. As shown in Figures 15 and 16, the telescoping member 605 is movably coupled to the transmission mechanism 7. The transmission mechanism 7 drives the telescopic member 605 to move in the axial direction. Specifically, as shown in FIG. 15, when the transmission mechanism 7 is rotated in one direction, the telescopic member 605 receives the direction. The rotation moves toward the longitudinal front end, at which time the blade 601 is in an unfolded state. The corresponding suction device 1 is in the suction mode, and the unfolded blade 601 can perform the pulverization. As shown in Fig. 16, when the transmission mechanism 7 is rotated in the other direction, the telescopic member 605 is acted upon to move toward the longitudinal rear end, at which time the blade 601 is in a contracted state. The contracted blade 601 can reduce the cross-sectional area occupied by the blade 601, thereby ensuring a sufficient air flow area. The corresponding suction device 1 is in the blow mode state. That is, when the suction device 1 is in the suction mode, the blade 601 is unfolded to perform pulverization. When the suction device 1 is in the blowing mode, the blade 601 contracts, thereby increasing the overwind area.
在另外的实施例中，粉碎机构6包括由柔性材料制成的打草绳。当传动机构7带动粉碎机构6围绕其轴线高速旋转时，由于离心力的作用，打草绳沿径向延伸，从而起到类似切割刀片的作用。如此设计打草绳同样起到粉碎效果。In a further embodiment, the comminuting mechanism 6 comprises a straw rope made of a flexible material. When the transmission mechanism 7 drives the pulverizing mechanism 6 to rotate at a high speed around its axis, the grass rope extends in the radial direction due to the centrifugal force, thereby functioning like a cutting blade. This design of the straw rope also plays a crushing effect.
即使有粉碎机构6的粉碎作用，粉碎的细小颗粒在通过马达4时仍然会对马达4造成损害。在某些极端的条件下，吸模式时吸入的气流可能会携带少量的水渍和水汽。该水渍和水汽所产生的潮湿也会对马达4产生明显的影响。为此，本发明的吹吸装置1还对马达4进行优化设计，使得马达4与气流通道55隔离设置。在如图2所示的一个实施例中，马达4位于气流通道55中，吹吸装置1包括一位于外壳14内部的马达罩44。马达罩44内部形成密闭的内部空间，马达4即处于内部空间中，而气流通道位于马达罩44外。因此马达罩44把马达4与气流通道55隔离开。气流从位于马达罩44与外壳14之间的气流通道55通过，而马达4始终位于马达罩44内不会受到影响。气流通道55中的杂质或者水汽不会影响到位于马达罩44内的马达4。在如图18的另外个一个实施例中，马达4直接设置在气流通道55外，从而避免气流通道55中的杂质或者水汽对其的影响。因此在该实施例中，马达4也可以不设置密封的马达罩44。如图10所示，马达罩44可以包括两个可相互固定连接的半壳，当然在其他实施例中，马达罩44也可以一体形成。另外，马达罩44由于包裹马达4，马达罩44位于风扇3的靠近第一开口12的一侧。Even if there is a pulverizing action of the pulverizing mechanism 6, the pulverized fine particles may cause damage to the motor 4 when passing through the motor 4. Under certain extreme conditions, the airflow drawn in the suction mode may carry a small amount of water and moisture. The moisture generated by the water and water vapor also has a significant effect on the motor 4. To this end, the suction device 1 of the present invention also optimizes the design of the motor 4 such that the motor 4 is disposed in isolation from the air flow passage 55. In one embodiment as shown in FIG. 2, the motor 4 is located in the airflow passage 55, and the air suction device 1 includes a motor cover 44 located inside the outer casing 14. The inside of the motor cover 44 forms a closed internal space, the motor 4 is in the internal space, and the air flow passage is located outside the motor cover 44. The motor cover 44 thus isolates the motor 4 from the air flow passage 55. Airflow passes from the airflow passage 55 between the motor cover 44 and the outer casing 14, and the motor 4 is always within the motor cover 44 without being affected. Impurities or moisture in the air flow passage 55 do not affect the motor 4 located within the motor cover 44. In another embodiment as shown in Fig. 18, the motor 4 is disposed directly outside the air flow passage 55, thereby avoiding the influence of impurities or moisture in the air flow passage 55. Therefore, in this embodiment, the motor 4 may not be provided with a sealed motor cover 44. As shown in FIG. 10, the motor cover 44 can include two half-shells that can be fixedly coupled to each other. Of course, in other embodiments, the motor cover 44 can also be integrally formed. In addition, since the motor cover 44 wraps the motor 4, the motor cover 44 is located on the side of the fan 3 close to the first opening 12.
为了对位于马达罩44内的马达4产生理想的冷却效果，吹吸装置1的内部还设有冷却通道，冷却通道用于引导冷却气流通过马达4从而达到冷却效果。在本实施例中，冷却气流使用的冷却通道与风扇3产生的气流使用的气流通道相对独立设置。如此可以保证冷却气流和风扇3产生的气流相互独立运行移动， 互不干扰。为此，如图1、图4和图5所示，冷却通道具有设置在外壳14上的进气口141和出气口142。进气口141和出气口142相对独立设置，进气口141和出气口142与外壳14上的接口11和第一开口12设置位置不同。进气口141和出气口142分别与马达罩44连通。具体地，在吹模式下，如图4所示，冷却空气从进气口141进入马达罩44内部并对马达4进行冷却，然后离开马达罩44并经出气口142回到外界，如图4中的空心箭头所示。而风扇3产生的气流从第一开口12进入主体10，然后从风管2的管口21吹出，如图4中的单线箭头所示。而在吸模式下，空气连同异物从风管2的管口21吸入气流通道，然后从第一开口12排出，如图5中的单线箭头所示。而冷却空气仍然从进气口141进入马达罩44，并带着马达4工作产生的热量从出气口142回到外界，如图5中的空心箭头所示。在本实施例中，进气口141和出气口142均位于外壳14的纵向中段。进气口141和出气口142围绕周向均匀分布在外壳14上。进气口141和出气口142大致呈栅格状开口设置。进气口141和出气口142相对沿纵向前后分布。进气口141相对出气口142更靠近外壳14的纵向前端，出气口142相当进气口141更靠近外壳14的纵向后端。在优选的实施例中，如图2所示，吹吸装置1还包括设置于马达罩44内的冷却风扇43。冷却风扇43可受马达4的驱动而旋转产生冷却气流。冷却风扇43连接于马达4的马达轴42。冷却风扇43优选地位于马达4的纵向后端。In order to produce a desired cooling effect on the motor 4 located in the motor cover 44, the inside of the suction device 1 is also provided with a cooling passage for guiding the cooling airflow through the motor 4 to achieve a cooling effect. In the present embodiment, the cooling passages used for the cooling airflow are relatively independently disposed with the airflow passages used by the airflow generated by the fan 3. This ensures that the cooling airflow and the airflow generated by the fan 3 move independently of each other. Do not interfere with each other. To this end, as shown in FIGS. 1, 4, and 5, the cooling passage has an intake port 141 and an air outlet 142 provided on the outer casing 14. The air inlet 141 and the air outlet 142 are relatively independently disposed, and the air inlet 141 and the air outlet 142 are disposed at different positions from the interface 11 and the first opening 12 on the outer casing 14. The intake port 141 and the air outlet 142 are in communication with the motor cover 44, respectively. Specifically, in the blowing mode, as shown in FIG. 4, the cooling air enters the inside of the motor cover 44 from the air inlet 141 and cools the motor 4, and then leaves the motor cover 44 and returns to the outside through the air outlet 142, as shown in FIG. The hollow arrow in the figure is shown. The airflow generated by the fan 3 enters the main body 10 from the first opening 12, and is then blown out from the nozzle 21 of the air duct 2, as indicated by the single-line arrow in FIG. In the suction mode, air and foreign matter are drawn into the air flow passage from the nozzle 21 of the air duct 2, and then discharged from the first opening 12 as indicated by a single-line arrow in FIG. The cooling air still enters the motor cover 44 from the air inlet 141, and returns heat from the air outlet 142 to the outside with the heat generated by the operation of the motor 4, as indicated by the hollow arrow in FIG. In the present embodiment, the air inlet 141 and the air outlet 142 are both located in the longitudinal middle section of the outer casing 14. The intake port 141 and the air outlet 142 are evenly distributed on the outer casing 14 around the circumference. The air inlet 141 and the air outlet 142 are arranged in a substantially grid-like opening. The intake port 141 and the air outlet 142 are distributed forward and backward in the longitudinal direction. The air inlet 141 is closer to the longitudinal front end of the outer casing 14 with respect to the air outlet 142, and the air outlet 142 is closer to the longitudinal rear end of the outer casing 14 than the air inlet 142. In a preferred embodiment, as shown in FIG. 2, the suction device 1 further includes a cooling fan 43 disposed within the motor cover 44. The cooling fan 43 can be rotated by the motor 4 to generate a cooling airflow. The cooling fan 43 is connected to the motor shaft 42 of the motor 4. The cooling fan 43 is preferably located at the longitudinal rear end of the motor 4.
如图10所示，马达罩44上设有容纳马达轴42穿出的传动接口45，从而方便位于马达罩44内部的马达4与位于马达罩44外部的风扇3连接。传动接口45沿轴线41方向设置。该传动接口45的截面积较小，仅可以容纳马达轴42穿过，这样又不影响马达罩44的密封性。马达罩44优选地是由左右两个半壳固定连接形成。该两个半壳通过固定螺栓或其他常见的固定方式固定连接。另外，冷却风扇43也位于马达罩44的内部。As shown in FIG. 10, the motor cover 44 is provided with a transmission interface 45 for accommodating the motor shaft 42 so as to facilitate connection of the motor 4 located inside the motor cover 44 to the fan 3 located outside the motor cover 44. The transmission interface 45 is disposed in the direction of the axis 41. The transmission interface 45 has a small cross-sectional area and can only accommodate the passage of the motor shaft 42 so as not to affect the sealing of the motor cover 44. The motor cover 44 is preferably formed by a fixed connection of the left and right half shells. The two half-shells are fixedly connected by fixing bolts or other common fixing means. In addition, the cooling fan 43 is also located inside the motor cover 44.
由于进气口141和出气口142都设置于外壳14上，而马达罩44位于外壳14的内部。为了保证两者之间的畅通连接，马达罩44上还设有冷却入口441和冷却出口442。冷却入口441与进气口141连通，而同时冷却出口442与出气口142连通。Since the air inlet 141 and the air outlet 142 are both disposed on the outer casing 14, the motor cover 44 is located inside the outer casing 14. In order to ensure a smooth connection between the two, the motor cover 44 is further provided with a cooling inlet 441 and a cooling outlet 442. The cooling inlet 441 is in communication with the intake port 141 while the cooling outlet 442 is in communication with the air outlet 142.
在本实施例中，冷却出口442和出气口142大小和位置对应设置。优选地， 马达罩44上的冷却出口442对准外壳14上的出气口142。使得冷却空气从冷却出口442排出马达罩44后直接通过出气口142排向外界。如图9和图10所示，马达罩44包括若干从罩体表面向外凸出的凸起部48。凸起部48的端部可以直接抵接到外壳14的内表面。外壳14内部的凸起部48***则仍然为风扇3产生的气流流通的部分。冷却出口442位于凸起部48的端部。而在外壳14受到凸起部48抵接的位置正好设有出气口142。若干个出气口142和冷却出口442沿周向布置。在本实施例中，马达罩44大致沿纵向延伸。而凸起部48沿垂直于纵向的径向延伸。换句话说，凸起部48沿轴线41的周向均匀分布。本实施例中的凸起部48数量为4个，相邻两个凸起部48之间的夹角为90度。当然凸起部48的数量也可以3、5、6等。如图9所示，空气在通过凸起部48时，空气从凸起部48和壳体14之间的间隙通过，该部分的间隙构成气流通道55的一部分。而由于在吸模式下，马达罩44及凸起部48位于风扇3的下游区域，并且空气从凸起部48的周围通过，因此凸起部48也可以起到类似导流的效果。同样地，为了减少共振叠加效应，使得凸起部48和叶片32的数量设置互为质数。例如，凸起部48的数量为4个，而叶片32的数量为11个。又例如，凸起部48的数量为5个，而叶片32的数量为12个。如此在风扇3进行转动工作的时候，在任意一时刻，叶片32和凸起部48在相位上重叠的数量至多为一。在吸模式下冷却空气进入马达罩44后从凸起部48向冷却出口442移动，并最终从出气口142流向外界。在其他实施例中，马达罩44的冷却出口442也可以不直接对准外壳14上的出气口142，而是通过一段通道后再从出气口142排出。In the present embodiment, the size and position of the cooling outlet 442 and the air outlet 142 are correspondingly arranged. Preferably, The cooling outlet 442 on the motor cover 44 is aligned with the air outlet 142 on the outer casing 14. The cooling air is discharged from the cooling outlet 442 to the motor cover 44 and directly discharged to the outside through the air outlet 142. As shown in Figures 9 and 10, the motor cover 44 includes a plurality of raised portions 48 that project outwardly from the surface of the cover. The end of the boss 48 can directly abut the inner surface of the outer casing 14. The periphery of the boss 48 inside the outer casing 14 is still the portion through which the airflow generated by the fan 3 flows. The cooling outlet 442 is located at the end of the boss 48. The air outlet 142 is provided at a position where the outer casing 14 is abutted by the boss portion 48. A plurality of air outlets 142 and cooling outlets 442 are arranged in the circumferential direction. In the present embodiment, the motor cover 44 extends substantially in the longitudinal direction. The raised portion 48 extends in a radial direction perpendicular to the longitudinal direction. In other words, the bosses 48 are evenly distributed along the circumferential direction of the axis 41. The number of the bosses 48 in this embodiment is four, and the angle between the adjacent two bosses 48 is 90 degrees. Of course, the number of the bosses 48 can also be 3, 5, 6, and the like. As shown in FIG. 9, air passes through the gap between the boss 48 and the housing 14 as it passes through the boss 48, and the gap of this portion constitutes a portion of the air passage 55. Since the motor cover 44 and the boss portion 48 are located in the downstream region of the fan 3 in the suction mode, and air passes around the boss portion 48, the boss portion 48 can also exert a similar flow guiding effect. Similarly, in order to reduce the resonance superposition effect, the number of the bosses 48 and the blades 32 are set to be prime numbers. For example, the number of the bosses 48 is four, and the number of the blades 32 is eleven. For another example, the number of the bosses 48 is five, and the number of the blades 32 is twelve. Thus, at any time when the fan 3 performs the turning operation, the number of the blades 32 and the bosses 48 overlapping in phase is at most one. After the cooling air enters the motor cover 44 in the suction mode, it moves from the boss portion 48 to the cooling outlet 442, and finally flows from the air outlet port 142 to the outside. In other embodiments, the cooling outlet 442 of the motor cover 44 may not be directly aligned with the air outlet 142 on the outer casing 14, but may be discharged from the air outlet 142 through a passage.
在本实施例中，进气口141并非直接对准冷却入口441，而是沿纵向错开一定距离或者沿垂直纵向的周向错开一定距离。因此，如图4至图6所示，在冷却入口441和进气口141之间还设有引导通道80。冷却空气在冷却入口441和进气口141之间的流通均通过该引导通道80。换句话说，冷却空气在进入外壳14后通过该引导通道80才进入马达罩44。而构成该引导通道80的则是导流罩53和外壳14之间的间隙。而由于风扇3产生的气流从导流罩53内部通过，而冷却空气从该引导通道80通过，因此导流罩53仍然可以使冷却空气与风扇3产生的吹吸气流分隔设置。在本实施例中，涵道5的导流罩53的配合部59包裹在马达罩44上。当然在其他实施例中，导流罩53也可以与马达罩44完全 分开设置。导流罩53上设有基本贴合冷却进口441的冷却进口441’。空气从进气口141进入外壳14的内部，然后在外壳14与导流罩53之间的空隙移动，并经过冷却进口441、441’进入到马达罩44内部。在本实施例中，该冷却进口441’设置在配合部59上。In the present embodiment, the air inlet 141 is not directly aligned with the cooling inlet 441, but is shifted by a certain distance in the longitudinal direction or a certain distance in the circumferential direction of the vertical direction. Therefore, as shown in FIGS. 4 to 6, a guide passage 80 is further provided between the cooling inlet 441 and the intake port 141. The flow of cooling air between the cooling inlet 441 and the intake port 141 passes through the guide passage 80. In other words, the cooling air enters the motor cover 44 through the guide passage 80 after entering the outer casing 14. What constitutes the guide passage 80 is a gap between the shroud 53 and the outer casing 14. Since the airflow generated by the fan 3 passes through the inside of the shroud 53, and the cooling air passes through the guide passage 80, the shroud 53 can still separate the cooling air from the blowing airflow generated by the fan 3. In the present embodiment, the fitting portion 59 of the shroud 53 of the duct 5 is wrapped around the motor cover 44. Of course, in other embodiments, the shroud 53 can also be completely integral with the motor cover 44. Set separately. The shroud 53 is provided with a cooling inlet 441' which substantially conforms to the cooling inlet 441. Air enters the interior of the outer casing 14 from the air inlet 141 and then moves within the gap between the outer casing 14 and the shroud 53 and enters the interior of the motor shroud 44 through the cooling inlets 441, 441'. In the present embodiment, the cooling inlet 441' is provided on the fitting portion 59.
吹吸装置1具有至少两种工作模式:吹模式和吸模式。在吹模式下，风管2通过接口11与主体10固定连接。风扇3可控制地围绕其轴线沿第一方向旋转，从而产生气流。控制风扇3旋转方向的方式当然优选是控制开关91。空气从第一开口12进入到主体10内部，然后通过马达罩44与外壳14之间的气流通道55及风扇3。该马达罩44与外壳14之间的气流通道55形成吹模式下的风扇3的上游区域。由于马达罩44的密封作用，空气并不会进入到马达罩44的内部。当空气从上游区域通过风扇3后，空气从导流罩53内部通过。具体地，导流体51和导流罩53之间的内部空间构成供气体通过的气流通道55，该部分的气流通道55形成吹模式下的下游区域。空气最终从风管2的管口21吹出。The suction device 1 has at least two modes of operation: a blow mode and a suction mode. In the blowing mode, the duct 2 is fixedly connected to the main body 10 via the interface 11. The fan 3 is controllably rotatable about its axis in a first direction to create an air flow. The manner of controlling the direction of rotation of the fan 3 is of course preferably the control switch 91. Air enters the interior of the body 10 from the first opening 12 and then passes through the air flow passage 55 and the fan 3 between the motor cover 44 and the outer casing 14. The air flow passage 55 between the motor cover 44 and the outer casing 14 forms an upstream region of the fan 3 in the blow mode. Due to the sealing action of the motor cover 44, air does not enter the interior of the motor cover 44. After the air passes through the fan 3 from the upstream region, the air passes through the inside of the shroud 53. Specifically, the internal space between the flow guiding body 51 and the shroud 53 constitutes an air flow passage 55 through which the gas passes, and the portion of the air flow passage 55 forms a downstream region in the blowing mode. The air is finally blown out from the nozzle 21 of the duct 2.
在吸模式下，风管2仍然通过连接口11与主体10固定连接。风扇3可控制地围绕其轴线沿第二方向旋转，从而产生气流。第二方向与第二方向是不同的。控制风扇3旋转方向的方式优选为控制开关91。空气连通树叶等异物从风管2的管口21进入，然后通过导流体51和导流罩53之间的气流通道55。该气流通道55形成该吸模式下风扇3的上游区域。在通过风扇3后，进入马达罩44与外壳14之间的气流通道55。该部分区域形成吸模式下的下游区域。最终从下游区域移动到主体10的第一开口12排出。在此模式下，第一开口12优选地连接有如垃圾袋等收集装置，垃圾树叶连同空气从第一开口12排出后可进入垃圾袋进行回收处理。In the suction mode, the duct 2 is still fixedly connected to the main body 10 through the connection port 11. The fan 3 is controllably rotatable about its axis in a second direction to create an air flow. The second direction is different from the second direction. The manner of controlling the direction of rotation of the fan 3 is preferably the control switch 91. Foreign matter such as air communication leaves enters from the nozzle 21 of the duct 2, and then passes through the air flow passage 55 between the fluid guide 51 and the shroud 53. The air flow passage 55 forms an upstream region of the fan 3 in the suction mode. After passing through the fan 3, it enters the air flow passage 55 between the motor cover 44 and the outer casing 14. This partial region forms a downstream region in the suction mode. Eventually moving from the downstream region to the first opening 12 of the body 10 is discharged. In this mode, the first opening 12 is preferably connected to a collecting device such as a garbage bag, and the garbage leaves, together with the air discharged from the first opening 12, can enter the garbage bag for recycling.
在传统的吹吸装置中，当吹吸装置执行吸模式时，收集装置安装连接在吹吸装置上。而在吹吸装置执行吹模式时，收集装置需要从吹吸装置上拆卸下来。因此遇到一些需要频繁切换吹吸模式的工况时，收集装置就相应需要从吹吸装置上频繁的拆装。如图39和图40所示，在本实施例中，无论吹吸装置1处于吹模式还是吸模式，收集装置200可以连接在吹吸装置1上。收集装置1包括了收集部201和可相对收集部移动的进气部202。收集部201用于收集垃圾，而进气部202用于使收集装置200内外的空气流通。如图40所示，在吹吸装置 1处于吸模式时，空气与垃圾的移动方向如图40中的箭头所示。进气部202收纳于收集部201内，此时从吹吸装置1吸入的垃圾可直接进入收集部201进行收集。如图39所示，而当吹吸装置1切换至吹模式时，空气的移动方向如图39中的箭头所示。进气部202移动至露出收集部201。吹吸装置1执行吹风所需要的空气通过进气部202进入到吹吸装置1中。如此，收集装置201始终连接吹吸装置1上，无需拆卸即可实现吹吸模式转换。在本实施例中，收集装置200还包括与吹吸装置1安装连接的安装部203。收集装置200通过安装部203始终与吹吸装置1连接。安装部203优选地固定设置在进气部202。安装部203可以是卡钩结构。卡钩结构使得进气部202与吹吸装置1固定连接。而收集部201上设有操作部204，使得用户通过该操作部204操纵收集部201相对进气部202进行移动。在本实施例中，操作部204为安装在收集部201上的把手。用户通过握持把手带动收集部201相对进气部202进行移动。在本实施例中，收集部201可相对进气部202枢转移动。收集装置200包括分别连接收集部201和进气部202的枢转轴205，从而使得收集部201与进气部202相对枢转轴205转动。如图39所示，进气部202通过安装部203固定安装到吹吸装置1的第一开口12。在本实施例中，第一开口12朝下设置。收集部201与进气部202相对枢转轴205形成一定角度，使得进气部202露出于收集部201外。此时，吹吸装置1处于吹风模式，外界的空气通过进气部202进入到吹吸装置1的第一开口12。如图40所示，吹吸装置1切换到吸风模式时，操作操作部204围绕枢转轴205转动，从而使得收集部201相对进气部202转动，进气部202被收集部201收纳在其中。在该吸模式下，从第一开口12排出的树叶、灰尘和垃圾进入至收集部201中。值得注意的是，收集部201优选地设有第二安装部206。第二安装部206与吹吸装置1固定连接。第二安装部206优选地为与安装部203类似的卡钩结构。在本实施例中，收集部201为具有由软性材料构成的袋子。袋子具有袋口207，树叶垃圾通过袋口207被收集入袋子中。当不进行收集时，袋子可折叠压缩成较小的收纳体积，便于收藏。常见的构成袋子的材料可以是无纺布等。进气部202设置在袋子的袋口207附近。进气部202可以是硬性材料构成。进气部202上设有进气孔208，便于气体流通。当然，在另外的一个实施例中，也可以选择性的把进气部202始终设置在吹吸装置1上，使得进气 部202作为吹吸装置1的一部分而固定不变。在该实施例中，进气孔208也相应设置在吹吸装置1上。In a conventional suction device, when the suction device performs the suction mode, the collection device is mounted and attached to the suction device. When the blowing device performs the blowing mode, the collecting device needs to be detached from the blowing device. Therefore, when encountering some conditions that require frequent switching of the blowing mode, the collecting device needs to be frequently disassembled from the blowing device. As shown in Figs. 39 and 40, in the present embodiment, the collecting device 200 can be attached to the blowing device 1 regardless of whether the blowing device 1 is in the blowing mode or the suction mode. The collecting device 1 includes a collecting portion 201 and an intake portion 202 movable relative to the collecting portion. The collecting portion 201 is for collecting garbage, and the intake portion 202 is for circulating air inside and outside the collecting device 200. As shown in Figure 40, in the suction device 1 When in the suction mode, the direction of movement of air and garbage is as indicated by the arrow in FIG. The intake unit 202 is housed in the collecting unit 201, and the garbage sucked from the air suction device 1 can be directly collected into the collecting unit 201 for collection. As shown in Fig. 39, when the suction device 1 is switched to the blowing mode, the moving direction of the air is as indicated by the arrow in Fig. 39. The intake portion 202 moves to the exposed collecting portion 201. The air required to perform the blowing by the suction device 1 enters the suction device 1 through the intake portion 202. In this way, the collecting device 201 is always connected to the blowing device 1, and the blowing mode switching can be realized without disassembly. In the present embodiment, the collecting device 200 further includes a mounting portion 203 that is mounted and coupled to the blowing device 1. The collecting device 200 is always connected to the suction device 1 through the mounting portion 203. The mounting portion 203 is preferably fixedly disposed at the intake portion 202. The mounting portion 203 may be a hook structure. The hook structure allows the inlet portion 202 to be fixedly coupled to the suction device 1. The collecting unit 201 is provided with an operating unit 204, so that the user manipulates the collecting unit 201 to move relative to the intake unit 202 through the operating unit 204. In the present embodiment, the operation portion 204 is a handle attached to the collecting portion 201. The user moves the collecting portion 201 relative to the intake portion 202 by holding the handle. In the present embodiment, the collecting portion 201 is pivotally movable relative to the intake portion 202. The collecting device 200 includes a pivoting shaft 205 that connects the collecting portion 201 and the intake portion 202, respectively, such that the collecting portion 201 and the intake portion 202 rotate relative to the pivoting shaft 205. As shown in FIG. 39, the intake portion 202 is fixedly attached to the first opening 12 of the air suction device 1 by the mounting portion 203. In the present embodiment, the first opening 12 is disposed downward. The collecting portion 201 forms an angle with the intake portion 202 with respect to the pivot shaft 205 such that the intake portion 202 is exposed outside the collecting portion 201. At this time, the air suction device 1 is in the air blowing mode, and the outside air enters the first opening 12 of the air suction device 1 through the air intake portion 202. As shown in FIG. 40, when the suction device 1 is switched to the suction mode, the operation operating portion 204 is rotated about the pivot shaft 205, so that the collecting portion 201 is rotated relative to the intake portion 202, and the intake portion 202 is received by the collecting portion 201 therein. . In the suction mode, leaves, dust, and garbage discharged from the first opening 12 enter the collecting portion 201. It is to be noted that the collecting portion 201 is preferably provided with the second mounting portion 206. The second mounting portion 206 is fixedly coupled to the suction device 1. The second mounting portion 206 is preferably a hook structure similar to the mounting portion 203. In the present embodiment, the collecting portion 201 is a bag having a soft material. The bag has a pocket 207 through which the leaf trash is collected into the bag. When not collected, the bag can be folded and compressed into a smaller storage volume for easy collection. A common material constituting the bag may be a nonwoven fabric or the like. The intake portion 202 is disposed near the pocket 207 of the bag. The intake portion 202 may be constructed of a rigid material. An air inlet 208 is provided in the air inlet portion 202 to facilitate gas circulation. Of course, in another embodiment, the inlet portion 202 can also be selectively disposed on the suction device 1 so that the intake air The portion 202 is fixed as part of the air suction device 1. In this embodiment, the air intake holes 208 are also provided correspondingly on the air suction device 1.
下面揭示如何组装吹吸装置的方法。如图32至图38所示，该种方法包括以下步骤：S1步骤，装配第一组件。第一组件主要包括风扇3、涵道5、粉碎机构6以及用于连接风扇3和粉碎机构6的传动机构7。S1步骤把该些元件组装成组件。S1步骤中包括S11、S12和S13三个子步骤。具体地，如图32所示的在S11子步骤中，把风扇3安装在传动机构7的第一端711。在本实施例中，传动机构7为传动轴71，传动轴71具有相对的两端，分别设定该两端为第一端711和相对的第二端712。把传动机构7的第一端711与风扇3沿图32中的虚线延伸方向不可相对转动的连接。传动机构7的第一端711与风扇3的连接孔33具有可相互连接的扁方结构或者花键结构等配接结构。另外在传动轴71上还安装有支撑轴承72。支撑轴承72的位置通常位于传动轴71的第一端和第二端之间。支撑轴承72的数量包括两个。两个支撑轴承72间隔一定距离的支撑传动轴71。如图33所示，在风扇3安装到传动轴71后，进行S12子步骤。在该步骤中，传动轴71***涵道5。由于在本实施例中，涵道5为一体式设计，整个涵道5包括导流体51、静叶片52和导流罩53为一体成型形成的零件。因此，传动轴71只能以***的方式与涵道5配接。传动轴72的第二端从涵道5的尾部沿图中虚线方向***导流体51中，并向涵道5的头部移动。导流体51的内表面设有凸起的定位结构。传动轴72上的支撑轴承72与导流体51内的一些定位结构卡接。定位结构可以是定位台阶、定位凸台等。如图34所示，在传动轴71与涵道5配接后，传动轴71的第二端712能够穿出涵道5的头部。而传动轴71的第一端711仍然位于涵道5的尾部之外。连接传动轴71的第一端711的风扇3也位于涵道5之外。传动轴71穿过涵道5，尤其是贯穿了涵道5的导流体51。在S13子步骤中，把粉碎机构6沿图中虚线方向安装在传动机构7的第二端。粉碎机构6具有安装部61，与传动机构7的第二端形配连接。这里的形配连接可以是扁方或者花键连接。因此，粉碎机构6设置在靠近涵道5的头部，而风扇3设置在靠近涵道5的尾部。为了防止粉碎机构6相对传动机构7的轴向移动，在传动机构7的第二端安装完粉碎机构6再安装有防滑结构74。由此第一组件安装完成，即S1步骤完成。 The method of assembling the suction device is disclosed below. As shown in FIGS. 32 to 38, the method includes the following steps: Step S1, assembling the first component. The first component mainly comprises a fan 3, a duct 5, a pulverizing mechanism 6, and a transmission mechanism 7 for connecting the fan 3 and the pulverizing mechanism 6. The S1 step assembles the components into components. The S1 step includes three sub-steps of S11, S12 and S13. Specifically, in the sub-step S11 shown in FIG. 32, the fan 3 is mounted at the first end 711 of the transmission mechanism 7. In the embodiment, the transmission mechanism 7 is a transmission shaft 71. The transmission shaft 71 has opposite ends, and the two ends are respectively set as a first end 711 and an opposite second end 712. The first end 711 of the transmission mechanism 7 is connected to the fan 3 in a rotationally fixed manner along the direction of the dashed line in FIG. The first end 711 of the transmission mechanism 7 and the connecting hole 33 of the fan 3 have a mating structure such as a flat structure or a spline structure that can be connected to each other. Further, a support bearing 72 is attached to the drive shaft 71. The position of the support bearing 72 is typically located between the first end and the second end of the drive shaft 71. The number of support bearings 72 includes two. The two support bearings 72 are spaced apart to support the drive shaft 71. As shown in Fig. 33, after the fan 3 is mounted to the drive shaft 71, the sub-step S12 is performed. In this step, the drive shaft 71 is inserted into the duct 5. Since the duct 5 is of an integrated design in the present embodiment, the entire duct 5 includes the fluid guide 51, the vane 52 and the shroud 53 as integrally formed parts. Therefore, the drive shaft 71 can only be mated with the duct 5 in an inserted manner. The second end of the drive shaft 72 is inserted into the fluid guide 51 from the tail of the duct 5 in the direction of the broken line in the figure, and moves toward the head of the duct 5. The inner surface of the fluid guiding body 51 is provided with a convex positioning structure. The support bearing 72 on the drive shaft 72 is engaged with some of the positioning structures within the fluid guide 51. The positioning structure may be a positioning step, a positioning boss, or the like. As shown in FIG. 34, after the drive shaft 71 is mated with the duct 5, the second end 712 of the drive shaft 71 can pass through the head of the duct 5. The first end 711 of the drive shaft 71 is still outside the tail of the duct 5. The fan 3 that connects the first end 711 of the drive shaft 71 is also located outside the duct 5. The drive shaft 71 passes through the duct 5, in particular the flow conductor 51 which runs through the duct 5. In the sub-step S13, the pulverizing mechanism 6 is attached to the second end of the transmission mechanism 7 in the direction of the broken line in the figure. The comminuting mechanism 6 has a mounting portion 61 that is in a form-fitting connection with the second end of the transmission mechanism 7. The form connection here can be a flat or splined connection. Therefore, the pulverizing mechanism 6 is disposed near the head of the duct 5, and the fan 3 is disposed near the tail of the duct 5. In order to prevent the axial movement of the pulverizing mechanism 6 relative to the transmission mechanism 7, the pulverizing mechanism 6 is mounted at the second end of the transmission mechanism 7 and the anti-slip structure 74 is attached. Thereby the first component installation is completed, ie the S1 step is completed.
在S2步骤中，装配第二组件。如图35所示，第二组件主要包括了马达4以及马达罩44。S2步骤主要包括S21和S22两个子步骤。由于马达罩44包括两个半壳，在S21子步骤中，把马达4固定安装到一个马达罩半壳中，在马达4和马达罩半壳中都对应设有定位作用的筋条，使得马达4能够固定安装在马达罩半壳中。在S22子步骤中，把另外的马达罩半壳与S21子步骤中的马达罩半壳沿图中双头线方向对接，并通过固定元件例如螺丝固定。第二组件安装完成，至此S2步骤完成。In the step S2, the second component is assembled. As shown in FIG. 35, the second assembly mainly includes a motor 4 and a motor cover 44. The S2 step mainly includes two sub-steps S21 and S22. Since the motor cover 44 includes two half-shells, in the sub-step S21, the motor 4 is fixedly mounted in a motor cover half-shell, and the positioning ribs are correspondingly arranged in the motor 4 and the motor cover half-shell, so that the motor 4 can be fixedly mounted in the motor cover half-shell. In the sub-step S22, the additional motor cover half-shell is abutted with the motor cover half-shell in the sub-step S21 in the direction of the double-headed line in the figure, and is fixed by a fixing member such as a screw. The second component is installed and the S2 step is completed.
在S3步骤中，把第一组件和第二组件连接起来。如图36所示，具体地，把第二组件中伸出马达罩44的马达轴42与第一组件中的风扇3配接。风扇3的连接孔33为通孔，其一侧连接传动机构7，另一侧则和电机轴42连接。连接的具体方式可以是前述提及的的扁方连接或者花键连接。完成连接后，第一组件和第二组件大致沿纵向前后排列。In the step S3, the first component and the second component are connected. As shown in Fig. 36, in particular, the motor shaft 42 extending from the motor cover 44 in the second assembly is mated with the fan 3 in the first assembly. The connecting hole 33 of the fan 3 is a through hole, one side of which is connected to the transmission mechanism 7, and the other side is connected to the motor shaft 42. The specific manner of attachment may be the aforementioned flat or splined connection. After the connection is completed, the first component and the second component are arranged substantially in the longitudinal direction.
在S4步骤中，把连接起来的第一组件和第二组件安装到外壳半壳中。如图36所示，类似地，外壳半壳具有配合第一组件和第二组件的定位结构。定位结构可以是定位筋条等。同时控制马达4运动方式的控制开关也通过电线连接至马达4的电路引脚上。In the step S4, the joined first and second components are mounted in the outer casing half-shell. As shown in Fig. 36, similarly, the outer casing half-shell has a positioning structure that cooperates with the first component and the second component. The positioning structure may be a positioning rib or the like. A control switch that simultaneously controls the manner in which the motor 4 moves is also connected to the circuit pins of the motor 4 by wires.
在S5步骤中，如图36所示，把另一个外壳半壳和S4中的半壳外壳沿图中双头线方向拼接并通过固定元件固定连接。如此就完成了吹吸装置1的主体10的装配。In the step S5, as shown in Fig. 36, the other outer casing half-shell and the half-shell outer casing in S4 are spliced in the direction of the double-headed line in the figure and fixedly connected by the fixing member. This completes the assembly of the body 10 of the suction device 1.
如图17和图18所示的另外一种实施例的吹吸装置，该实施例中的吹吸装置1与图1所示的吹吸装置的结构基本相同。下面就两实施例的不同作出说明：在本实施例中，构成粉碎机构6的切割刀片的第一侧边681和第二侧边682呈弧形弯曲，从而使整个切割刀片大致呈S型。同时，切割刀片也具有更小截面面积，在本实施例中，第一侧边681和对应的第二侧边682之间具有更短的间距，优选地最大的间距小于20毫米。涵道5的配合部59具有规则结构，整个配合部59类似漏斗结构，具有半径逐渐增大的锥形体591和位于连接锥形体591末端的圆筒形的裙边体592构成。在锥形体591还开设冷却进口441’。而在第一开口12处还设有安全护罩121。安全护罩121位于马达罩44的纵向后端。图18所示为图17中的吹吸装置的剖视图。从该图中可以看出，连接粉碎 机构6和风扇3的传动轴71穿过涵道5设置。而传动轴71上设有起支撑作用的支撑轴承72。支撑轴承72上还设有减振元件73。减振元件73的作用是削弱传动轴71产生的振动传递给涵道5。减振元件73可以套接在支撑轴承72上的橡胶圈或者橡胶帽等。The suction device of the other embodiment shown in Figs. 17 and 18 has the same structure as that of the suction device shown in Fig. 1. The following description will be made on the difference between the two embodiments: In the present embodiment, the first side 681 and the second side 682 of the cutting blade constituting the pulverizing mechanism 6 are curved in an arc shape, so that the entire cutting blade is substantially S-shaped. At the same time, the cutting blade also has a smaller cross-sectional area. In this embodiment, there is a shorter spacing between the first side 681 and the corresponding second side 682, preferably a maximum spacing of less than 20 mm. The fitting portion 59 of the duct 5 has a regular structure, and the entire fitting portion 59 is similar to a funnel structure, and has a tapered body 591 having a gradually increasing radius and a cylindrical skirt body 592 at the end of the connecting tapered body 591. A cooling inlet 441' is also formed in the cone 591. A safety shield 121 is also provided at the first opening 12. The safety shield 121 is located at the longitudinal rear end of the motor cover 44. Figure 18 is a cross-sectional view showing the suction device of Figure 17. As can be seen from the figure, the connection is smashed The mechanism 6 and the drive shaft 71 of the fan 3 are disposed through the duct 5. The drive shaft 71 is provided with a supporting bearing 72 for supporting. A damping element 73 is also provided on the support bearing 72. The function of the damping element 73 is to weaken the vibration generated by the transmission shaft 71 and transmit it to the duct 5. The damping element 73 can be sleeved on a rubber ring or a rubber cap or the like that supports the bearing 72.
如图18所示，风扇3到涵道5的静叶片52之间的间距优选为5mm～20mm。其中，间距L定义为静叶片52的末端到风扇3转动形成且经过风扇中3中心的平面P之间纵向距离。静叶片52的末端是指静叶片52靠近风扇3的一端。静叶片52具有一定具有一定的纵向长度，静叶片52的末端是指沿纵向方向上最靠近风扇3的端部。风扇3旋转形成垂直于风扇轴线39的转动平面P，由于风扇轴线39沿纵向设置，因此风扇3的转动平面P延伸方向与纵向垂直，而且风扇3的转动平面P经过风扇3的中心C。另外，定义风扇3的叶片32的自由端36的宽度为弦长d，如图3所示。在本实施例中，间距L与弦长d的比值为0.3至1.5，可以保证吹吸装置1的吹风性能较高。如果比值小于0.3，说明间距L较短，说明风扇3太靠近涵道5，不能充分发挥风扇3的性能，从而不利于产生较高的吹风效率。而如果比值大于1.5，说明间距L较长，说明风扇3太远离涵道5，同样不利于产生高吹风效率。优选地，间距L与弦长d的比值为0.6时，吹风效率最高。以静叶片52的弦长d为21mm为例，当间距L为6.3mm时，即比值为0.3时，吹吸装置1产生的风速约为42m/s。而当间距达到12.6mm时，即比值为0.6时，吹吸装置1产生的风速约为45m/s。因此，可以看到随着比值的增大，风速得到一定程度的提高，从而提升效率。而当间距L为18.9mm时，即比值为0.9时，吹吸装置1产生的风速约为42m/s，由此可见当比值继续增大时，风速反而又开始下降。当间距L为约为31.5mm时，即比值为1.5时，吹吸装置1产生的风速位于36m/s，由此可以看到，风速显著的下降，工作效率并不理想。因此，最佳实施例为比例在0.6左右，风扇3的叶片32的弦长为21mm时，间距L优选为12.6mm，此时工作效率最高。As shown in Fig. 18, the distance between the fan 3 and the stationary vanes 52 of the duct 5 is preferably 5 mm to 20 mm. The pitch L is defined as the longitudinal distance between the end of the stationary vane 52 and the plane P formed by the rotation of the fan 3 and passing through the center of the fan 3 . The end of the stationary vane 52 refers to the end of the stationary vane 52 near the fan 3. The stationary vane 52 has a certain longitudinal length, and the end of the stationary vane 52 refers to the end closest to the fan 3 in the longitudinal direction. The fan 3 is rotated to form a plane of rotation P perpendicular to the fan axis 39. Since the fan axis 39 is disposed longitudinally, the plane of rotation P of the fan 3 extends perpendicularly to the longitudinal direction, and the plane of rotation P of the fan 3 passes through the center C of the fan 3. In addition, the width of the free end 36 of the blade 32 defining the fan 3 is the chord length d, as shown in FIG. In the present embodiment, the ratio of the pitch L to the chord length d is 0.3 to 1.5, and the blowing performance of the air suction device 1 can be ensured to be high. If the ratio is less than 0.3, the spacing L is short, indicating that the fan 3 is too close to the duct 5, and the performance of the fan 3 cannot be fully exerted, which is disadvantageous for generating a high blowing efficiency. If the ratio is greater than 1.5, the distance L is longer, indicating that the fan 3 is too far away from the duct 5, which is also disadvantageous for generating high air blowing efficiency. Preferably, when the ratio of the pitch L to the chord length d is 0.6, the blowing efficiency is the highest. Taking the chord length d of the stationary vane 52 as 21 mm as an example, when the pitch L is 6.3 mm, that is, when the ratio is 0.3, the wind speed generated by the suction device 1 is about 42 m/s. When the pitch reaches 12.6 mm, that is, when the ratio is 0.6, the air blowing device 1 generates a wind speed of about 45 m/s. Therefore, it can be seen that as the ratio increases, the wind speed is increased to some extent, thereby improving efficiency. When the distance L is 18.9 mm, that is, when the ratio is 0.9, the wind speed generated by the suction device 1 is about 42 m/s, so that when the ratio continues to increase, the wind speed starts to decrease. When the pitch L is about 31.5 mm, that is, when the ratio is 1.5, the wind speed generated by the suction device 1 is 36 m/s, whereby it can be seen that the wind speed is remarkably lowered, and the work efficiency is not satisfactory. Therefore, in the preferred embodiment, the ratio is about 0.6, and when the chord length of the blade 32 of the fan 3 is 21 mm, the pitch L is preferably 12.6 mm, and the working efficiency is the highest at this time.
由于在吹模式下，涵道5位于风扇3的下游区域，从风扇3吹出的气流通过涵道5时产生整流作用，从而可以调整部分气流的旋向，减少涡流的产生，使整体气流方向更齐整，提升气流的吹风效果和效率。具体地，由于空气需先后通过涵道5的静叶片52以及风扇3的叶片32，静叶片52和风扇3的叶片32 都是围绕轴线周向设置。为了避免两者在周向上的相互干扰，确保其在周向的任意相位上不会有叶片的较多重合而产生类似的共振叠加效应，使得静叶片52和叶片32的数量设置互为质数。如果静叶片52与叶片32的数量存在非1或者非其本身的约数，则静叶片52和叶片32在某一时刻可能多个相位相同，从而产生类似共振叠加效应的扰流，影响气流的稳定性。在本实施例中，静叶片52的数量优选为5～8片。如果静叶片52的设置数量如果过少的话，例如4片、3片，则会有一部分空气直接从两两静叶片52之间的空隙穿过，而没有被静叶片52导流，造成局部涡流的产生，影响整体气流的吹风效率。而如果静叶片52的设置数量较多的话，例如9片、10片，虽然导流效果较好，但是由于静叶片52过于密集，影响了空气在气流通道55的过风面积，使得气体流动不通畅，降低了风速。在本实施例中，静叶片52的数量优选为6片。而对应的风扇3的叶片32数量为11片，如此可以保证两者的数量互为质数。在另外一个实施例中，静叶片52的数量7个，而叶片32的数量对应为12个。如此在风扇3进行转动工作的时候，在任意一时刻，叶片32和静叶片52在相位上重叠的数量至多为一。Since the duct 5 is located in the downstream area of the fan 3 in the blowing mode, the airflow blown from the fan 3 is rectified when passing through the duct 5, so that the direction of the partial airflow can be adjusted, the generation of the eddy current can be reduced, and the overall airflow direction can be further improved. Tightening, improving the air blowing effect and efficiency of the airflow. Specifically, since the air needs to pass through the stationary vanes 52 of the duct 5 and the vanes 32 of the fan 3, the vanes 52 of the vane 52 and the fan 3 They are all circumferentially arranged around the axis. In order to avoid mutual interference between the two in the circumferential direction, it is ensured that there is no more overlap of the blades in any phase in the circumferential direction to produce a similar resonance superposition effect, so that the number of the stationary blades 52 and the blades 32 are set to be prime numbers. If the number of stationary vanes 52 and vanes 32 is not one or not a divisor of their own, the stationary vanes 52 and vanes 32 may have multiple phases at a certain time, thereby generating a spoiler like a resonance superposition effect, affecting the airflow. stability. In the present embodiment, the number of the stationary vanes 52 is preferably 5 to 8 pieces. If the number of the stationary vanes 52 is too small, for example, 4 pieces or 3 pieces, a part of the air passes directly from the gap between the two stationary vanes 52 without being diverted by the stationary vanes 52, causing local eddy currents. The generation, affecting the overall airflow efficiency. On the other hand, if the number of the stationary blades 52 is large, for example, 9 pieces and 10 pieces, although the flow guiding effect is good, since the static blades 52 are too dense, the air passing area of the air flow passage 55 is affected, so that the gas flow is not Smooth, reducing wind speed. In the present embodiment, the number of the stationary vanes 52 is preferably six. The number of blades 32 of the corresponding fan 3 is 11, so that the number of the two is mutually prime. In another embodiment, the number of stationary vanes 52 is seven, and the number of vanes 32 corresponds to twelve. Thus, at any moment when the fan 3 performs the turning operation, the number of the blades 32 and the stationary blades 52 overlapping in phase is at most one.
另外值得注意的是，为了进一步隔离冷却通道与气流通道55，防止气流在相互串通，马达罩44还包括密封件443。密封件443设置在马达罩44的传动接口45处。设置传动接口45的原因是使马达轴42通过该传动接口45向外穿出以与风扇3传动连接。由于传动接口46的径向尺寸必然大于马达轴42的径向尺寸，因此传动接口46与马达轴42之间存在间隙，马达罩44外部的气流通道55中的部分空气可以通过该间隙进入到马达罩44内部，从而干扰了气流通道55与冷却通道的独立设置。如图所示，在传动接口46处设置有密封件443，密封件443能够把气流通道55与冷却通道隔离设置，防止该两个通道内的气流通过该传动接口46相互流通。在本实施例中，密封件443为桶形结构。筒形结构的圆周侧壁为实体的桶壁。位于筒臂延伸方向的两端均为开口设置。因此密封件443呈贯通设置的桶形结构。马达轴42从密封件443的内部中空贯穿通过。密封件443的一端安装连接于传动接口46，另一端位于马达罩44的内部。具体地，密封件443的该端连接于支撑马达4的支撑结构46。进一步地，密封件443抵接于支撑结构46的前支架461。前支架461上设有支撑马达轴42的支撑 轴承464，支撑轴承464仅容纳马达轴42无间隙的穿过。因此，支撑轴承464能够把密封件443的该端开口密封，把马达罩44内部与马达罩44外部隔离。同时并不会影响马达轴42的传动作用。如此设计，位于马达罩44外部的气流通道55中的气流由于密封件443的桶壁以及支撑轴承464的阻挡作用无法进入到马达罩44的内部。而马达罩44内部的冷却通道的气流也由于密封件443的桶壁以及支撑轴承464的阻挡作用无法流动至马达罩44的外部。因此通过密封件443可以保证气流通道55和冷却通道的独立性，防止其相互干扰，进一步提升工作效率。而密封件443连接传动接口45以及支撑结构46的结构可以是凸台、卡槽等形配的卡接连接结构。It is also worth noting that in order to further isolate the cooling passages from the air flow passages 55 to prevent the airflow from colluding with each other, the motor cover 44 further includes a seal 443. The seal 443 is disposed at the transmission interface 45 of the motor cover 44. The reason for providing the transmission interface 45 is to allow the motor shaft 42 to pass outwardly through the transmission interface 45 for transmission connection with the fan 3. Since the radial dimension of the transmission interface 46 is necessarily greater than the radial dimension of the motor shaft 42, there is a gap between the transmission interface 46 and the motor shaft 42, through which a portion of the air in the air flow passage 55 outside the motor cover 44 can enter the motor. The inside of the cover 44 interferes with the independent arrangement of the air flow passage 55 and the cooling passage. As shown, a seal 443 is provided at the transmission interface 46 that is configured to isolate the airflow passage 55 from the cooling passages to prevent airflow within the two passages from flowing through the transmission interface 46. In the present embodiment, the seal 443 is a barrel structure. The circumferential side wall of the cylindrical structure is a solid barrel wall. Both ends in the direction in which the barrel arms extend are provided with openings. Therefore, the sealing member 443 has a barrel structure that is disposed through. The motor shaft 42 is hollowly passed through from the inside of the seal 443. One end of the seal 443 is mounted to the transmission interface 46 and the other end is located inside the motor cover 44. Specifically, the end of the seal 443 is coupled to the support structure 46 that supports the motor 4. Further, the seal 443 abuts against the front bracket 461 of the support structure 46. The front bracket 461 is provided with a support for supporting the motor shaft 42 Bearing 464, support bearing 464 only accommodates the passage of motor shaft 42 without play. Thus, the support bearing 464 can seal the end opening of the seal 443 to isolate the interior of the motor cover 44 from the exterior of the motor cover 44. At the same time, it does not affect the transmission of the motor shaft 42. So designed, the air flow in the air flow passage 55 outside the motor cover 44 cannot enter the inside of the motor cover 44 due to the blocking effect of the barrel wall of the seal 443 and the support bearing 464. The air flow of the cooling passage inside the motor cover 44 also cannot flow to the outside of the motor cover 44 due to the blocking effect of the barrel wall of the seal 443 and the support bearing 464. Therefore, the independence of the air flow passage 55 and the cooling passage can be ensured by the sealing member 443 to prevent mutual interference, thereby further improving work efficiency. The structure of the sealing member 443 connecting the transmission interface 45 and the supporting structure 46 may be a snap-fit connection structure such as a boss or a card slot.
在如图19所示的实施例中，吹吸装置1还可以包括把涵道5移除气流通道的移除机构以及可容纳涵道5的容纳腔100。在风管为单管的吹吸装置1中，把涵道5设置成可移动的是一个优选的方案。涵道5可选择地移动进入气流通道55或者移除气流通道55。在气流通道55附近还优选地设置有可完全容纳涵道5的容纳腔100。当涵道5移动至容纳腔后，涵道5就完全离开气流通道55。从而保证在吸风时气流通道55的畅通。当涵道5移动至气流通道55中后，吹风时涵道5可以对经过的气流起导流作用。移除机构使涵道5移动的方式也可以包括平移或者转动的方式。在平移的实施例中，移除机构可以包括使涵道5滑动的导轨以及控制涵道5在导轨上滑动的控制件。在转动的实施例中，移除机构可以包括类似左轮***中的***机构。操作转动机构可以使涵道5整体地围绕一轴线旋转移位，从而使涵道5移除气流通道。也是旋转涵道5又回复至位于气流通道中的位置。该轴线可以位于涵道5中心以外的位置。并且旋转的角度也可以优选地为90度、180度等。In the embodiment shown in FIG. 19, the suction device 1 may further include a removal mechanism for removing the air passage from the duct 5 and a housing chamber 100 for accommodating the duct 5. In the blowing device 1 in which the duct is a single tube, it is a preferred solution to arrange the duct 5 to be movable. The duct 5 is selectively moved into the air flow passage 55 or the air flow passage 55 is removed. A receiving chamber 100 that can completely accommodate the duct 5 is also preferably provided adjacent to the air flow passage 55. When the duct 5 is moved to the accommodating chamber, the duct 5 completely leaves the air passage 55. Thereby, the smooth flow of the air flow passage 55 at the time of suction is ensured. When the duct 5 is moved into the air flow passage 55, the duct 5 can act as a guide for the passing airflow. The manner in which the removal mechanism moves the duct 5 may also include a translation or rotation. In the translated embodiment, the removal mechanism can include a rail that slides the duct 5 and a control that controls the duct 5 to slide over the rail. In a rotating embodiment, the removal mechanism can include a clip mechanism similar to that in a revolver. Operating the rotating mechanism can rotationally displace the duct 5 integrally about an axis such that the duct 5 removes the air passage. It is also the position where the rotating duct 5 is returned to the air passage. The axis can be located outside the center of the duct 5. And the angle of rotation may also preferably be 90 degrees, 180 degrees or the like.
如图20所示的另外一个实施例中，吹吸装置1的马达4位于马达壳体143中，风扇3的风扇轴线39和马达4的轴线41相互平行设置。为了实现两者的传动作用，马达4与风扇3之间另外设置有传动件47。马达4通过传动件47带动风扇3旋转。此处的传动件47可以是常见的皮带或者锥齿轮等可以改变传动角度的元件。风扇3与马达4并非纵向前后排列，而是风扇3与马达4沿纵向并排设置。如此可以使吹吸装置1的整体纵向尺寸减少，并且使马达4并非位于空气流通经过的路径中。本领域技术人员容易想到的是，也可以使风扇3 的风扇轴线39和马达4的轴线41呈一定的角度设置，例如锐角。而风管2与之前的实施例一样。In another embodiment as shown in Fig. 20, the motor 4 of the suction device 1 is located in the motor housing 143, and the fan axis 39 of the fan 3 and the axis 41 of the motor 4 are disposed in parallel with each other. In order to achieve the transmission of the two, a transmission member 47 is additionally provided between the motor 4 and the fan 3. The motor 4 drives the fan 3 to rotate through the transmission member 47. The transmission member 47 herein may be a conventional belt or bevel gear or the like that can change the transmission angle. The fan 3 and the motor 4 are not vertically aligned, but the fan 3 and the motor 4 are arranged side by side in the longitudinal direction. This makes it possible to reduce the overall longitudinal dimension of the suction device 1 and to make the motor 4 not located in the path through which the air circulates. It will be readily apparent to those skilled in the art that the fan 3 can also be The fan axis 39 and the axis 41 of the motor 4 are arranged at an angle, such as an acute angle. The duct 2 is the same as the previous embodiment.
在如图21所示的另一实施例中，吹吸装置1’同样包括风管2’和主体10’。风管2’的数量同样为一根。风管2’的一端为管口21’，另外一端为用于连接主体10’的连接头22。与上一实施例不同的是，主体10’上具有至少两个不同的连接口，分别为第一连接口18和第二连接口19。并且风管的连接头22可选择地与第一连接口18和第二连接口19进行配接。优选地，第一连接口18和第二连接口19分别位于主体10’内的风扇3’的两侧。第一连接口18和第二连接口19在垂直风扇3’的风扇轴线39’的平面上的投影至少部分相同。风管2’通过选择相应的连接口与进行连接后，吹吸装置1’也自然切换到相应工作模式。例如，当风管2’的连接头22与主体10’的第一连接口18连接时，吹吸装置1’即处于吹模式。当马达4’开始工作后，风扇3’产生的气流经第一连接口18从风管2’的管口21’吹出。当风管2’的连接头22与主体的第二连接口19连接时，吹吸装置1’即切换到吸模式。当工作开始工作后，气流从风管2’的管口21’吸入并通过第二连接口19。值得注意的是，在本实施例中，风扇3’在吹或吸模式下无需改变旋转方向，始终只需沿一个方向旋转。吹模式下的气流通道与吸模式下的气流通道并不相同。风扇3’优选地包括轴流风扇、混流风扇等能够产生沿风扇的轴向移动的气流。当然，主体10’和风管2’可以优选地可拆卸的连接。在不需要工作的时候，主体10’和风管2’可拆卸为两个独立的部件分别进行存储，在需要工作的时候，风管2’则选择与主体10’的其中一个连接口固定连接。在图22所示的另一实施例中，风管2’可以与主体10’相对转动的形式与主体10’连接。主体10’上设有枢转轴13，枢转轴13可带动风管2’围绕其轴线转动到不同的位置。从而实现风管2’与其中的一个连接口连接。在本优选的实施例中，风管2’从连接第一连接口18的位置转动至连接第二连接口19的位置过程中，转动的角度为180度。当然本领域技术人员可以想到的是采用实现风管与主体相对线性移动的结构。In another embodiment as shown in Fig. 21, the suction device 1' also includes a duct 2' and a body 10'. The number of ducts 2' is also one. One end of the air duct 2' is a nozzle 21', and the other end is a connector 22 for connecting the main body 10'. Different from the previous embodiment, the main body 10' has at least two different connecting ports, respectively a first connecting port 18 and a second connecting port 19. And the connector 22 of the duct is selectively mated with the first connector 18 and the second connector 19. Preferably, the first connection port 18 and the second connection port 19 are respectively located on both sides of the fan 3' in the main body 10'. The projection of the first connection port 18 and the second connection port 19 on the plane of the fan axis 39' of the vertical fan 3' is at least partially identical. After the air duct 2' is connected and connected by selecting the corresponding connection port, the air suction device 1' is also naturally switched to the corresponding operation mode. For example, when the connector 22 of the duct 2' is connected to the first port 18 of the main body 10', the suction device 1' is in the blowing mode. When the motor 4' starts operating, the airflow generated by the fan 3' is blown out from the nozzle 21' of the air duct 2' via the first connection port 18. When the connector 22 of the air duct 2' is connected to the second connector 19 of the main body, the air suction device 1' is switched to the suction mode. When the work starts working, the airflow is drawn in from the nozzle 21' of the duct 2' and passed through the second port 19. It is to be noted that, in the present embodiment, the fan 3' does not need to change the direction of rotation in the blowing or suction mode, and it is only necessary to rotate in one direction at all times. The airflow channel in the blow mode is not the same as the airflow channel in the suction mode. The fan 3' preferably includes an axial flow fan, a mixed flow fan or the like that is capable of generating an air flow that moves in the axial direction of the fan. Of course, the body 10' and the duct 2' may preferably be detachably connected. When the work is not required, the main body 10' and the air duct 2' are detachably stored as two separate components, and when the work is required, the air duct 2' is selectively connected to one of the main body 10'. . In another embodiment shown in Fig. 22, the duct 2' can be coupled to the body 10' in a form that is relatively rotatable with the body 10'. The body 10' is provided with a pivot shaft 13 which can drive the air duct 2' to rotate about its axis to different positions. Thereby, the duct 2' is connected to one of the joints. In the preferred embodiment, the angle of rotation is 180 degrees during the rotation of the duct 2' from the position where the first connection port 18 is connected to the position where the second connection port 19 is connected. Of course, it is conceivable by those skilled in the art to adopt a structure that realizes a relatively linear movement of the duct and the body.
如图25所示为本发明的另一实施例。在该实施例中，吹吸装置1包括了第一风扇310和第二风扇320，并且第一风扇310和第二风扇320都位于主体10内。马达4位于第一风扇310和第二风扇320之间，且分别和第一风扇310、 第二风扇320连接。马达轴42与第一风扇31和第二风扇32之间设有离合装置60。主体10上开设有第一开口260和第二开口270。在本实施例中，出口管423和螺旋通道424都设置在主体10上，并且靠近主体10的第二开口270设置。在优选的实施例中，可以采用同一根风管430作为吹风管和吸风管。当处于吹模式时，把该风管430安装到第一开口260，马达4驱动第一风扇310工作，气流从该风管吹出。当切换到吸模式时，把该风管430从第一开口260卸下，并安装到第二开口270上，马达4驱动第二风扇320工作，空气从该风管430吸入并从主体10上的出口管423排出。Another embodiment of the present invention is shown in FIG. In this embodiment, the suction device 1 includes a first fan 310 and a second fan 320, and both the first fan 310 and the second fan 320 are located within the body 10. The motor 4 is located between the first fan 310 and the second fan 320, and is respectively associated with the first fan 310, The second fan 320 is connected. A clutch device 60 is disposed between the motor shaft 42 and the first fan 31 and the second fan 32. The main body 10 is provided with a first opening 260 and a second opening 270. In the present embodiment, the outlet tube 423 and the spiral passage 424 are both disposed on the body 10 and disposed adjacent to the second opening 270 of the body 10. In a preferred embodiment, the same duct 430 can be employed as the blower and suction duct. When in the blowing mode, the duct 430 is mounted to the first opening 260, and the motor 4 drives the first fan 310 to operate, and the airflow is blown out from the duct. When switching to the suction mode, the duct 430 is detached from the first opening 260 and mounted to the second opening 270, the motor 4 drives the second fan 320 to operate, and air is drawn from the duct 430 and from the main body 10. The outlet pipe 423 is discharged.
如图26为本发明的另一实施例。在该实施例中，仍然把一根风管430作为吹风管或者吸风管。与第五实施例所不同的是，吹吸装置1设有连接风管与主体10的枢转装置107。枢转装置107可控制风管430相对主体10改变位置。枢转装置107给围绕枢转轴130转动。枢转装置107还包括连接主体10的第一连接臂110以及连接风管430的第二连接臂120。如图26所示，当处于吹模式时，风管430移动至与第一风扇310配合的位置，此时风管430当做吹风管使用。当切换至吸模式时，无需把风管拆卸，通过枢转装置把风管移动至与第二风扇320配合的位置，此时风管430当做吸风管使用。Figure 26 is another embodiment of the present invention. In this embodiment, a duct 430 is still used as a blow pipe or a suction duct. Different from the fifth embodiment, the air suction device 1 is provided with a pivoting device 107 that connects the air duct with the main body 10. The pivoting device 107 can control the position of the duct 430 relative to the body 10. The pivoting device 107 rotates about the pivot axis 130. The pivoting device 107 further includes a first connecting arm 110 that connects the main body 10 and a second connecting arm 120 that connects the air duct 430. As shown in Fig. 26, when in the blowing mode, the duct 430 is moved to a position where it is engaged with the first fan 310, at which time the duct 430 is used as a blow pipe. When switching to the suction mode, it is not necessary to disassemble the air duct, and the air duct is moved to a position where the second fan 320 is engaged by the pivoting device, and the air duct 430 is used as the air suction duct.
图27为本发明的另一实施例。在该实施例中，仍然把一根风管430作为吹风管或者吸风管，并且该风管430在切换吹吸模式时无需移动位置，可以始终固定连接在主体10上。主体10内设有第一风扇310和第二风扇320。第一风扇310为轴流风扇，具有轴流叶片和第一转轴311。第二风扇320为离心风扇，具有离心叶片和第二转轴321。轴流风扇能够在马达4单独驱动轴流风扇旋转的吹风位置和在马达4同时驱动轴流风扇和离心风扇的吸风位置之间移动。第二风扇320上设有容纳第一风扇31的容纳腔400。第一风扇310位于该容纳腔400内。第二风扇32上还设有连通容纳腔400和风管430的通道401。第一风扇310的第一转轴311和第二风扇320的第二转轴321与马达轴42之间设有离合装置。在吹模式下，马达轴42通过离合装置与第一转轴311动力连接，而与第二转轴321断开动力连接，从而马达4带动第一风扇310旋转。第一风扇310产生的气流通过第二风扇320的通道，并从风管430吹向外部。当切换至吸模式，马达轴42通过离合装置与第二转轴321动力连接，而与第一转轴311断开 动力连接。马达4可带动第二风扇32旋转，从而把气流从风管430吸入。Figure 27 is another embodiment of the present invention. In this embodiment, a duct 430 is still used as the blow pipe or the suction duct, and the duct 430 does not need to be moved when the blow mode is switched, and can be fixedly attached to the main body 10 at all times. A first fan 310 and a second fan 320 are disposed in the main body 10. The first fan 310 is an axial fan having an axial flow vane and a first rotating shaft 311. The second fan 320 is a centrifugal fan having a centrifugal blade and a second rotating shaft 321. The axial flow fan is movable between a blowing position at which the motor 4 separately drives the axial fan to rotate and a suction position at which the motor 4 simultaneously drives the axial fan and the centrifugal fan. The second fan 320 is provided with a receiving chamber 400 for accommodating the first fan 31. The first fan 310 is located within the receiving cavity 400. The second fan 32 is further provided with a passage 401 that communicates with the accommodating chamber 400 and the air duct 430. A clutch device is disposed between the first rotating shaft 311 of the first fan 310 and the second rotating shaft 321 of the second fan 320 and the motor shaft 42. In the blowing mode, the motor shaft 42 is dynamically coupled to the first rotating shaft 311 through the clutch device, and is disconnected from the second rotating shaft 321 so that the motor 4 drives the first fan 310 to rotate. The airflow generated by the first fan 310 passes through the passage of the second fan 320 and is blown from the duct 430 to the outside. When switching to the suction mode, the motor shaft 42 is dynamically connected to the second rotating shaft 321 through the clutch device, and is disconnected from the first rotating shaft 311. Power connection. The motor 4 can drive the second fan 32 to rotate, thereby drawing airflow from the air duct 430.
如图28为本发明的另一实施例。在该实施例中，吹吸装置仍然包括第一风扇310和第二风扇302。第一风扇310为轴流风扇，第二风扇320为离心风扇。第一风扇310可移动地与第二风扇302配合。在吹模式下，作为轴流风扇的第一风扇310进行工作，并不与第二风扇320配合。而作为离心风扇的第二风扇320不工作。在吸模式下，第一风扇310移动至与第二风扇320配合的位置，从而使第二风扇310与第二风扇320一起工作。如图28所示，第二风扇320具有容纳腔400，第一风扇310可沿第一转轴311轴向移动。当第一风扇310收容于第二风扇320的容纳腔400，第一风扇310的叶片与第二风扇320的叶片对齐，组成混流叶片。在吹模式下，第一风扇310单独工作并产生气流，而第二风扇320并不工作。在吸模式下，在第一风扇310的叶片与第二风扇320的叶片组合形成混流风扇的叶片，使得第一风扇310和第二风扇320整体构成混流风扇。马达4驱动第一风扇310和第二风扇320一起工作，从而使得混流风扇旋转工作，产生气流。Figure 28 is another embodiment of the present invention. In this embodiment, the suction device still includes a first fan 310 and a second fan 302. The first fan 310 is an axial fan and the second fan 320 is a centrifugal fan. The first fan 310 is movably mated with the second fan 302. In the blow mode, the first fan 310, which is an axial fan, operates without mating with the second fan 320. The second fan 320, which is a centrifugal fan, does not operate. In the suction mode, the first fan 310 moves to a position that cooperates with the second fan 320, thereby causing the second fan 310 to work with the second fan 320. As shown in FIG. 28, the second fan 320 has a receiving cavity 400, and the first fan 310 is axially movable along the first rotating shaft 311. When the first fan 310 is received in the accommodating cavity 400 of the second fan 320, the blades of the first fan 310 are aligned with the blades of the second fan 320 to form a mixed flow blade. In the blow mode, the first fan 310 operates alone and generates airflow, while the second fan 320 does not operate. In the suction mode, the blades of the first fan 310 and the blades of the second fan 320 are combined to form a blade of the mixed flow fan, such that the first fan 310 and the second fan 320 integrally constitute a mixed flow fan. The motor 4 drives the first fan 310 and the second fan 320 to work together, thereby causing the mixed flow fan to rotate to generate an air flow.
在如图23和图24所示的另一实施例中，吹吸装置1’同样包括风管2’、主体10’。风管2’的数量同样为一根。与上一实施例不同的是，位于风管2’两端的两个端口均可选择地与主体10’连接。为描述方便，风管2’的两个端口分别为第一端口23和第二端口24。主体10’上优选地仅设置有一个连接口25。通过风管2’的不同端口与主体10’的连接，吹吸装置相应切换工作模式。例如，当风管的第一端口23与主体10’上的连接口25连接后，此时，第二端口24作为风管2’的自由端，吹吸装置1’即处于吹模式。当马达4’驱动风扇3’工作后，气流从风管2’的第二端口24吹出。当风管2’的第二端口24与主体10’的连接口25连接后，风管2’的第一端口23又作为风管的自由端，吹吸装置1’即处于吸模式。当马达4’驱动风扇3’工作后，气流从风管2’的第一端口23吸入主体10’。当然，在该实施例中，风扇同样优选地包括轴流风扇、混流风扇等能够产生沿风扇的轴向移动的气流。与上一实施例不同的是，风扇3’能够沿两个不同的方向旋转。在吹模式下，风扇3’沿第一方向旋转，在吸模式下，风扇3’沿第二方向旋转。特别值得注意的是，在本实施例中，风管优选地不是笔直的管道，而粗细有变化。风管2’大致呈锥形，第一端口23的半径大于第二端口24的半 径，使得第一端口23的截面积大于第二端口24的截面积。如此在吹模式下，从截面积较小的第二端口24吹出的气流能够获得较高的风速，提升吹风的效果。而在吸模式下，从截面积较大的第一端口23吸入，能够防止异物在端口形成堵塞，影响吸风的效果。当然，为了使主体10’的连接口25能够与不同粗细的风管端口连接，连接口25具有匹配第一端口23的第一连接部26和匹配第二端口24的第二连接部27。在本实施例中，连接口25优选地具有类似台阶的阶梯结构或者类似漏斗的锥形结构。也就是说，第一连接部26和第二连接部27配合形成周向的阶梯结构或者形成半径渐变的锥形结构。另外值得注意的是，由于风管的不同端口配接连接口的位置不同，使得风管2’在吹吸不同模式下的有效长度而也有变化。有效长度是指从连接口到风管的自由端之间的距离。In another embodiment as shown in Figures 23 and 24, the suction device 1' also includes a duct 2', a body 10'. The number of ducts 2' is also one. Unlike the previous embodiment, two ports located at both ends of the duct 2' are selectively connectable to the main body 10'. For convenience of description, the two ports of the duct 2' are the first port 23 and the second port 24, respectively. Preferably, only one connection port 25 is provided on the main body 10'. Through the connection of the different ports of the duct 2' to the body 10', the blowing means switches the mode of operation accordingly. For example, when the first port 23 of the duct is connected to the connecting port 25 on the main body 10', at this time, the second port 24 serves as the free end of the duct 2', and the air suction device 1' is in the blowing mode. When the motor 4' drives the fan 3' to operate, the airflow is blown from the second port 24 of the duct 2'. When the second port 24 of the duct 2' is connected to the connection port 25 of the main body 10', the first port 23 of the duct 2' serves as the free end of the duct, and the air suction device 1' is in the suction mode. When the motor 4' drives the fan 3' to operate, airflow is drawn into the body 10' from the first port 23 of the duct 2'. Of course, in this embodiment, the fan also preferably includes an axial flow fan, a mixed flow fan, or the like that is capable of generating an air flow that moves in the axial direction of the fan. Unlike the previous embodiment, the fan 3' is rotatable in two different directions. In the blowing mode, the fan 3' rotates in the first direction, and in the suction mode, the fan 3' rotates in the second direction. It is particularly noteworthy that in the present embodiment, the duct is preferably not a straight pipe, but the thickness varies. The duct 2' is substantially conical, and the radius of the first port 23 is larger than the half of the second port 24. The diameter is such that the cross-sectional area of the first port 23 is larger than the cross-sectional area of the second port 24. Thus, in the blowing mode, the airflow blown from the second port 24 having a small cross-sectional area can obtain a higher wind speed and enhance the effect of blowing. In the suction mode, the suction from the first port 23 having a large cross-sectional area prevents the foreign matter from becoming clogged at the port and affects the effect of suction. Of course, in order to enable the connection port 25 of the main body 10' to be connected to a different thickness of the duct port, the connection port 25 has a first connection portion 26 that matches the first port 23 and a second connection portion 27 that matches the second port 24. In the present embodiment, the connection port 25 preferably has a stepped structure like a step or a tapered structure like a funnel. That is, the first connecting portion 26 and the second connecting portion 27 cooperate to form a circumferential stepped structure or a tapered structure having a radius gradation. It is also worth noting that due to the different positions of the different ports of the ducts, the effective length of the duct 2' in different modes of blowing is also varied. The effective length refers to the distance from the connection port to the free end of the duct.
在如图37所示的另一实施例中，吹吸装置1同样包括主体10和可拆卸的连接主体10的风管2。主体10上同样设有第一开口12。在主体10内设有气流产生装置用于产生气流。当吹吸装置1处于吹模式下，在气流产生装置的驱动下，空气从第一开口12进入主体10，并从连接主体10的风管2吹出。当吹吸装置1切换至吸模式下，在气流产生装置的驱动下，空气连同树叶和粉尘从风管2进入并从第一开口12排出。当然，第一开口12可以设置在主体10的不同位置。在本实施例中，气流产生装置包括对旋轴流机构500和用于驱动对旋轴流机构500的电机501。对旋轴流机构500包括至少一对轴流风扇。该对轴流风扇能够产生沿不同方向移动的气流，并且在吹模式时产生向风管2移动的气流，而在吸模式时产生向第一开口12移动的气流。对旋轴流机构500中的该对轴流风扇靠近设置，从而在相互之间产生对旋效果。该对轴流风扇包括第一轴流风扇502和第二轴流风扇503。第一轴流风扇502和第二轴流风扇503之间距离在0.01倍的轴流风扇直径到0.5倍的轴流风扇直径之间。第一轴流风扇502和第二轴流风扇503均能围绕各自的旋转轴线进行旋转。在本实施例中，第一轴流风扇502和第二轴流风扇503的旋转轴线重合，也就是说，第一轴流风扇502和第二轴流风扇503围绕同一旋转轴线旋转。在本发明实施例中，第一轴流风扇502和第二轴流风扇503总是同时被驱动旋转。进一步地，第一轴流风扇502与第二轴流风扇503沿相反的方向旋转。也就是说，当第一轴流风扇502顺时针转动时，第二轴流风扇503逆时针转动。而当第一轴流风扇502逆时针 转动时，第二轴流风扇503顺时针转动。由于第一轴流风扇502和第二轴流风扇503的对旋作用，因此通过旋轴流机构500的气流总是保持沿旋转轴线方向运动。In another embodiment as shown in Fig. 37, the suction device 1 also includes a main body 10 and a detachable duct 2 connecting the main body 10. A first opening 12 is also provided in the body 10. An air flow generating device is provided in the main body 10 for generating an air flow. When the air suction device 1 is in the blowing mode, air is driven from the first opening 12 into the main body 10 and blown from the air duct 2 of the connection main body 10 under the driving of the air flow generating device. When the suction device 1 is switched to the suction mode, air is introduced into the air duct 2 together with the leaves and dust and discharged from the first opening 12, driven by the airflow generating device. Of course, the first opening 12 can be disposed at different positions of the body 10. In the present embodiment, the airflow generating device includes a counter-rotating axial flow mechanism 500 and a motor 501 for driving the counter-rotating axial flow mechanism 500. The counter-rotating axial flow mechanism 500 includes at least one pair of axial fans. The pair of axial fans are capable of generating a flow of air moving in different directions, and generating a flow of air moving toward the duct 2 in the blow mode, and generating a flow of the air moving toward the first opening 12 in the suction mode. The pair of axial fans in the axial flow mechanism 500 are disposed close to each other to produce a counter-rotating effect between each other. The pair of axial fans includes a first axial fan 502 and a second axial fan 503. The distance between the first axial fan 502 and the second axial fan 503 is between 0.01 times the diameter of the axial fan and 0.5 times the diameter of the axial fan. Both the first axial fan 502 and the second axial fan 503 are rotatable about respective axes of rotation. In the present embodiment, the axes of rotation of the first axial fan 502 and the second axial fan 503 coincide, that is, the first axial fan 502 and the second axial fan 503 rotate about the same axis of rotation. In the embodiment of the invention, the first axial fan 502 and the second axial fan 503 are always driven to rotate at the same time. Further, the first axial fan 502 and the second axial fan 503 rotate in opposite directions. That is, when the first axial fan 502 rotates clockwise, the second axial fan 503 rotates counterclockwise. And when the first axial fan 502 is counterclockwise When rotated, the second axial fan 503 rotates clockwise. Due to the counter-rotation of the first axial fan 502 and the second axial fan 503, the air flow through the rotary shaft mechanism 500 always maintains movement in the direction of the rotation axis.
第一轴流风扇502和第二轴流风扇503具有若干个围绕旋转轴线周向布置的叶片。如图38所示，第一轴流风扇502的叶片旋向是沿图中箭头AA’方向，也就是逆时针方向。而第二轴流风扇503的叶片旋向是沿图中箭头BB’方向，也就是顺时针方向。因此，第一轴流风扇502和第二轴流风扇503的叶片旋向正好相反设置。如图39所示，当气流通过第一轴流风扇502时，由于轴流风扇的叶片旋向原因，气流总会向远离轴线的方向偏离。而该偏离的气流通过第二轴流风扇503时，由于第二轴流风扇503相反的旋向，使得该气流又向靠近轴线的方向移动。因此经过该两级轴流风扇的气流能够保证沿旋转轴线方向移动，因此在该实施例中，吹吸装置1并不需要再设置涵道机构进行导流。而由于没有涵道机构，在吸模式下，空气连同树叶粉尘等颗粒物直接在主体10内直接通过对旋轴流机构500，无需再通过额外的粉碎机构，从而可以提高颗粒物的通过效率。The first axial fan 502 and the second axial fan 503 have a plurality of blades circumferentially disposed about the axis of rotation. As shown in Fig. 38, the blade rotation direction of the first axial fan 502 is in the direction of the arrow AA' in the figure, that is, in the counterclockwise direction. The blade rotation direction of the second axial fan 503 is in the direction of the arrow BB' in the figure, that is, in the clockwise direction. Therefore, the blade rotation directions of the first axial fan 502 and the second axial fan 503 are arranged oppositely. As shown in Fig. 39, when the airflow passes through the first axial fan 502, the airflow always deviates away from the axis due to the blade rotation of the axial fan. When the deviated airflow passes through the second axial fan 503, the airflow moves toward the axis again due to the opposite direction of rotation of the second axial fan 503. Therefore, the airflow passing through the two-stage axial flow fan can ensure the movement in the direction of the rotation axis, so in this embodiment, the suction device 1 does not need to be provided with the ducting mechanism for conducting the flow. Since there is no ducting mechanism, in the suction mode, the air, together with the dust of the leaves, directly passes through the counter-rotating axial flow mechanism 500 directly in the main body 10, and there is no need to pass an additional pulverizing mechanism, thereby improving the passage efficiency of the particulate matter.
为了使电机501能够驱动第一轴流风扇502和第二轴流风扇503能够同时旋转，在如图37所示的实施例中，吹吸装置1还包括连接第一轴流风扇502和第二轴流风扇503的传动装置504。传动装置504一方面与电机501连接，另一方面可以同时带动第一轴流风扇502和第二轴流风扇503以相反方向旋转。如图40所示，传动装置504包括连接电机501的连接轴505、连接第一轴流风扇502的第一齿轮组506和连接第二轴流风扇503的第二齿轮组507。第一齿轮组506和第二齿轮组507均和连接轴505啮合传动。第一齿轮组506和第二齿轮组507具有不同的传动啮合方向与连接轴505传动连接。因此当连接轴505受到电机501驱动进行旋转时，能够带动第一齿轮组506和第二齿轮组507以相反方向转动，进而使得第一轴流风扇502与第二轴流风扇503同时以相反的方向转动。吹吸装置1还包括支撑所述连接轴505的支撑装置508。支撑装置508包括支架结构。在该实施例中可以看出，电机501的数量为一个。在吹模式下，用户控制电机501沿第一方向旋转，通过传动装置504的带动，第一轴流风扇502顺时针旋转的同时第二轴流风扇503逆时针旋转，因此整个对旋轴 流机构500产生向风管2吹出的气流。而在吸模式下，用户控制电机501沿与第一方向相反的第二方向旋转，则通过传动装置504，第一轴流风扇502沿逆时针旋转的同时第二轴流风扇503顺时针旋转，因此整个对旋轴流机构500产生从风管2吸入的气流。In order to enable the motor 501 to drive the first axial fan 502 and the second axial fan 503 to rotate simultaneously, in the embodiment shown in FIG. 37, the suction device 1 further includes a first axial fan 502 and a second. A transmission 504 of the axial fan 503. The transmission 504 is connected on the one hand to the motor 501, and on the other hand can simultaneously rotate the first axial fan 502 and the second axial fan 503 in opposite directions. As shown in FIG. 40, the transmission 504 includes a connecting shaft 505 that connects the motor 501, a first gear set 506 that connects the first axial fan 502, and a second gear set 507 that connects the second axial fan 503. Both the first gear set 506 and the second gear set 507 are meshed with the connecting shaft 505. The first gear set 506 and the second gear set 507 have different drive meshing directions for driving connection with the connecting shaft 505. Therefore, when the connecting shaft 505 is driven to rotate by the motor 501, the first gear set 506 and the second gear set 507 can be driven to rotate in opposite directions, so that the first axial fan 502 and the second axial fan 503 are opposite at the same time. The direction is rotated. The suction device 1 further includes a support device 508 that supports the connecting shaft 505. Support device 508 includes a stent structure. As can be seen in this embodiment, the number of motors 501 is one. In the blowing mode, the user controls the motor 501 to rotate in the first direction, and the first axial fan 502 rotates clockwise while the second axial fan 503 rotates counterclockwise by the transmission 504, so the entire countershaft The flow mechanism 500 generates an air flow that is blown to the air duct 2. In the suction mode, when the user controls the motor 501 to rotate in a second direction opposite to the first direction, the first axial fan 502 rotates counterclockwise through the transmission 504, and the second axial fan 503 rotates clockwise. Therefore, the entire counter-rotating axial flow mechanism 500 generates an air flow sucked from the air duct 2.
在如图41所示的实施例中，吹吸装置1同样具有包括了第一轴流风扇502和第二轴流风扇503的对旋轴流机构500。所不同的是，电机501包括了分开设置的第一电机509和第二电机510。第一电机509单独连接第一轴流风扇502并用于驱动第一轴流风扇502转动。第二电机510单独连接第二轴流风扇503并用于驱动第二轴流风扇503转动。吹吸装置1还包括控制第一电机509和第二电机510的控制机构511。控制机构511控制第一电机509和第二电机510以相反方向旋转，进而带动第一轴流风扇502与第二轴流风扇503沿相反方向转动。控制机构511可以以PCB板形式对两个电机进行驱动。在该实施例中，电机501的数量至少为两个。在其中的一个实施例中，如图42所示，第一电机509的负极和第二电机510的正极并联连接在控制机构511的一端的电性端子，而第一电机509的正极和第二电机510的负极并联连接在控制机构511的另一端的电性端子。当控制机构511移动至电路导通的第一位置时，第一电机509和第二电机510正好同时以相反的方向转动。而当控制机构511移动至电路导通的第二位置时，第一电机509和第二电机510同时各自改变旋转方向，于是第一电机509和第二电机510仍然保持相反的转向。In the embodiment shown in FIG. 41, the suction device 1 also has a counter-rotating axial flow mechanism 500 including a first axial fan 502 and a second axial fan 503. The difference is that the motor 501 includes a first motor 509 and a second motor 510 that are separately disposed. The first motor 509 is separately coupled to the first axial fan 502 and is used to drive the first axial fan 502 to rotate. The second motor 510 is separately coupled to the second axial fan 503 and is used to drive the second axial fan 503 to rotate. The suction device 1 further includes a control mechanism 511 that controls the first motor 509 and the second motor 510. The control mechanism 511 controls the first motor 509 and the second motor 510 to rotate in opposite directions, thereby driving the first axial fan 502 and the second axial fan 503 to rotate in opposite directions. The control mechanism 511 can drive the two motors in the form of a PCB. In this embodiment, the number of motors 501 is at least two. In one of the embodiments, as shown in FIG. 42, the anode of the first motor 509 and the anode of the second motor 510 are connected in parallel to the electrical terminals of one end of the control mechanism 511, and the anode and the second of the first motor 509. The negative electrode of the motor 510 is connected in parallel to an electrical terminal at the other end of the control mechanism 511. When the control mechanism 511 is moved to the first position where the circuit is conducting, the first motor 509 and the second motor 510 are simultaneously rotated in opposite directions. When the control mechanism 511 moves to the second position where the circuit is conducting, the first motor 509 and the second motor 510 simultaneously change the direction of rotation, respectively, so that the first motor 509 and the second motor 510 still maintain the opposite steering.
另外，本领域技术人员可以想到的是，在仅能执行吹风功能的吹风机中，也可以采用该种对旋轴流机构500，从而提高轴向吹风的性能。In addition, it is conceivable to those skilled in the art that in a hair dryer capable of performing only a blowing function, the pair of rotary axial flow mechanisms 500 can also be employed, thereby improving the performance of axial blowing.
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。 The above-mentioned embodiments are merely illustrative of several embodiments of the present invention, and the description thereof is more specific and detailed, but is not to be construed as limiting the scope of the invention.
